You can minimize entire tab groups by clicking on the color circle at the beginning of the tab group. Once you've created one or more tab groups, you can move entire tab groups within your web browser just by drag-and-dropping. Right-click on one of those tabs, select 'Add Tab to Group' in the drop-down menu, and then type the group name and select the color you want the group organized by. It essentially lets you organize your tabs like a color-coded filing system.
Called Tab Groups, the feature allows you to group tabs together and organize them by color, custom group name or even an emoji. Google introduced a tab grouping feature to Chrome within the past year that is a life saver if you're somebody who always has a zillion tabs open at a time.
This is another pro tip rather than a setting to change, but it's incredibly useful.
