@leocg I noticed that there is a similar feature after you mentioned it. My fault. I'm sorry, I didn't see it.

I am a university student. I usually use a lot of tabs. For example school, project, movie or game. I pin tabs and usually reuse them within 1 week. It is present in tabs that I use all the time and need to stay open. But when I'm at work, it's hard for me to switch between tabs because there are too many tabs. Maybe something like a category tab could be added. It's like the windows folder we know. When you click on that tab, the tabs you put sideways can be opened. In this way, university tabs, tabs I watch anime, e-books I read or youtube that I use while developing a project, etc. By categorizing the tabs, I can access them whenever I need them. It feels difficult to use bookmarks. Fixed tabs work easier.

This is just a recommendation. I want it if you can bring this update.
