Feature request: A better session / context management
We use the same browser for work, for a school study, while shopping or while trying to book hotels for a vacations. It's not uncommon to move between these contexts, which leaves the typical tabline with dozens of tabs open.
Performance issues aside, it makes using the browser feel cumbersome.
I believe working on such a feature would be great. A similar concept can be shown here https://refresh.study/

One thing you could do is to use separate windows for different things/subjects.
