When it comes to dark mode, Google Chrome will follow the lead of the operating system you’re running it on by default: If Windows or macOS is set in its dark mode configuration, then Chrome will adapt accordingly.
If you’d rather use Chrome in dark mode all the time, find the #enable-force-dark flag and set it to Enabled. Every site you visit from then on will get the message to show its contents in dark mode, no matter what the rest of your software is doing.
Google Lens is a visual search tool: It can identify landmarks, animals, storefronts, and much more. It’s available in various places, including as a mobile app, and with the right flag enabled you can take advantage of it in Chrome as well.
The flag you need to switch on is #enable-lens-region-search. Once that’s done, right-click on a blank part of any webpage, choose Search Images with Google Lens, and select the image you want to search with.
Enable the #tab-hover-card-images flag in the list and navigating between large numbers of tabs will suddenly become much easier.
As you hover the cursor over the tab, you’ll not only see the title of the webpage contained within it, but you’ll also see a pop-up thumbnail of the content it’s showing as well.
Chrome supports the grouping of tabs now, to help you manage them better. When you hide a group of tabs under the group header to tidy up your tab bar, that’s known as collapsing a tab group.
When enabled, the #tab-groups-collapse-freezing flag will freeze the tabs in a group when you collapse them. That means they’ll be in a hibernated state and not taking up any system resources until you open them again.
There’s a password manager built right into Google Chrome, which you can find by clicking on the three dots in the top right corner, then choosing Settings, Auto-fill, and Passwords.
Click on the three dots on the right just above the password list and you’ll find an option to export your passwords—if you want to be able to import passwords into Chrome too, enable the #password-import flag.
Parallel downloading is where an application requests a download several times, which should speed up transfer times in a lot of cases. If you don’t mind the extra bandwidth this can take up, you can switch on the feature by finding the #enable-parallel-downloading flag and switching it to Enabled.
