There are several additional features and tweaks in Chrome OS 91 that are not yet part of the default experience. They are likely not stable enough for everyone while they’re still in development. Google tucked some of these experimental features behind a page — and you can enable them right now. Activate these switches, or “flags,” by typing chrome://flags in Chrome’s URL bar and hitting enter. Here is a list of low-risk flags we’ve tested that we recommend trying out.
New flags to try on Chrome OS 91
Changes to our recommended Chrome flags list:
- chrome://flags/#enable-notification-indicator (default)
- chrome://flags/#enable-desktop-pwas-attention-badging-cros (default)
- chrome://flags/#ash-enable-pip-rounded-corners (expired)
- chrome://flags/#global-media-controls-picture-in-picture (merged into #global-media-controls-modern-ui)
There are more flags we recommend below, along with details that explain what each flag does.
Improve Linux (Beta)
Linux (Beta) operates in a container under Chrome OS, giving you access to an extensive selection of Linux apps like Inkscape, Audacity, and Steam. The following flag will help improve the Linux experience.
- Unable to play games on your Chromebook because of the frustrating cursor? Enable this Chrome flag to allow Linux applications to request the mouse pointer, necessary when playing Linux games on Chrome OS.
Chrome OS UI tweaks
Want to toggle on some new flags that bring cosmetic changes to the Chrome OS UI? This flag will round corners and enhance its looks.
- Google is testing a refreshed media controls UI that adapts to the video thumbnail’s primary colors. To make its design less drab on Chrome and Chrome OS, enable the modern UI flag.

- Google is experimenting with a dedicated emoji picker for Chrome OS that actually isn’t frustrating to use with a mouse. You can also search for emoji using the large search bar — a functionality missing from the old implementation. To make picking emoji less annoying, enable this Chrome flag.

- It’s frustrating to find out about your digital pen’s battery is low when you least expect it. To keep track of its battery, you can enable this Chrome flag. Its battery level will show up in your stylus settings, but your mileage may vary depending on your pen.

Improve productivity in Chrome OS
Chrome OS has several useful hidden tricks up its sleeves to enhance your productivity.
- We’ve all made that dreaded mistake of deleting the wrong file by accident. By default, Chromebooks doesn’t provide a way to restore the file or folder you removed. Enable this Chrome flag to add a trash folder to the file manager, which functions similar to the ever-iconic Recycle Bin found on Windows.

- PWAs are inching a step closer to feeling native with app shortcuts. While the feature became available for Chrome and Edge last year, it lacked support for Chrome OS. Enable this Chrome flag to get PWA app shortcuts for Chromebooks.

- Currently, the Chrome OS shell runs in the browser, which can add clutter to your Chrome tabs. Enable this Chrome flag to run it as a tabbed system web app.

- The scan app is a great way to digitize your physical documents. Enabling this Chrome flag will allow you to annotate your scanned papers quickly by opening the Media app.
- Google is working to add a clipboard to the Chrome OS virtual keyboard, helping you keep track of text of images you’ve copied. Enable this feature to get the clipboard manager into the virtual keyboard.

- Your Chromebook gives you different options for connecting to the web, but not every network provides unlimited data access. Chrome OS used to let you specify a rate-limited network, but it went away due to pending issues. Enable this Chrome flag to bring the toggle back.
- Moving apps to different pages in the Chrome OS launcher feels slippery and unpolished. To improve the launcher’s usability, Google is working on a new paging UI, making it easy to see where your app icons are going when moving them around. Enable this Chrome flag to see some of its improvements to the launcher.

Chrome productivity enhancements
Google Chrome is naturally the tightly integrated default web browser in Chrome OS. Here is a list of flags that enhance the web browsing experience.
- Sharing a block of text you’ve found online is a hassle, especially if it’s hard to find on a particularly long webpage. By enabling this flag, you can create a link that takes you directly to that text. Highlight a selection of words, right-click, and select “Copy link to highlight.”
- Permission requests for things like notifications can be intrusive and distracting. Enable this Chrome flag to activate a more modern, less annoying permission prompt.
Permission requests are a lot less annoying with the new design.
- Google announced Live Caption for Chrome OS 90, which generates real-time captions with accuracy. The feature is slowly making its way to users, but if you don’t want to wait, enable this Chrome flag. To transcribe audio, click “Manage accessibility features” in Chrome OS settings, select Captions, then toggle on Live Caption. English is the only language supported for now. If it complains that it can’t download speech files, you’ll need to disable chrome://flags/#enable-accessibility-live-caption-soda. This should make it work — at the cost of decreased transcribing accuracy.
Live Caption for Chromebooks transcribes audio in real-time — and it works offline, too.
- If you have a lot of tabs open, it’s sometimes difficult to distinguish between them. Enable this flag to show a preview of the web page when hovering your cursor over a Chrome tab, which is useful for quickly finding tabs.
Hovering your cursor over your Chrome tab will show a preview of that tab.
- Chrome OS launches PWAs into a single app window, which is annoying if you want to be productive. Enable this flag to add Chrome’s tab strip to PWAs to help speed up your workflow with multiple Chrome tabs.
Tabbed PWAs in Chrome OS makes it easier to multitask.
- Currently, launching a new tab in a PWA will create a new Chrome instance, breaking your focus. Enable this Chrome flag to fix links in PWAs.
- Need a certain PWA to launch after clicking on a link? Enabling this Chrome flag will allow you to prefer launching a PWA from your Chromebook.
- When hovering a cursor over links, Chrome displays a URL on the bottom left — even web apps. If you’d rather this not be the case so that web apps look more like native ones, enable this Chrome flag.
- If you manage your Google Account often, enable this Chrome flag to put a convenient shortcut to your Google account settings on the Chrome toolbar.

Improve scrolling in Chrome
Does scrolling feel rough when browsing through webpages using Chrome? Thanks to Microsoft Edge developers, the scrolling experience will be much smoother with these flags enabled.
- For the next step in porting Microsoft Edge’s scrolling improvements into Chrome, the Edge developers introduce percent-based mouse scrolling. This system fixes an issue where free-floating scroll wheels (like on a Logitech MX Master) would not correctly scroll. Enable it to improve the free-floating scroll on Chrome OS.
Get better Chromebook performance
Working with a slow machine is frustrating, especially when the battery doesn’t last very long. One of your Chromebook’s strengths is its lightweight nature, making the system feel more agile than most. There are a few flags that could speed up your Chromebook, but they may introduce security issues.
- Chrome OS disabled hyperthreading on a few Intel-based Chromebooks because of an MDS vulnerability with the CPU. Check Cog to see if it disabled a few of its cores. If the performance loss from the deactivated cores is too significant for your use-case, enable the flag to get the cores back – with caution.
- Recent Spectre variant 2 mitigations from Intel reduce the chance of your Chromebook being exploited by malicious actors. However, they could cause significant performance slowdowns on your machine. Deciding between speed or security isn’t easy, but if you need better CPU performance, you can disable this Chrome flag — with caution.
Improve Chrome’s performance
The Chrome web browser is agile and robust, but some people complain about their Chromebook’s performance. These sets of flags should slightly improve Chrome’s performance.
- Previously, Chrome caches media content to disk during acquisition and playback. Keeping the disk active increases power consumption and can prevent specific lower-power modes from being engaged. Enable this Chrome flag to prevent caching certain media content to disk to improve battery life slightly.
- Chromebooks with low RAM can run into performance hitches with several Chrome tabs opened in tab groups. Enable this Chrome flag to sleep tabs collapsed inside a tab group, reducing memory usage.
That’s about all the useful flags in Chrome OS 91 that we recommend trying. I cannot wait for these features to roll out to everyone, and I’m excited to see Chrome OS grow even further in the coming weeks and months.
