Something really interesting is beginning to emerge from this discussion. People have varying requirements in terms of transience/permanence. Some features, like tabs are less permanent, but still permanent enough for many uses. Other features like bookmarks are far more permanent, maybe even too permanent.

All of this is beginning to look like the communication tool hierarchy (calling, email, teams etc). There’s clearly a similar hierarchy of permanence, and when a given topic does not cross the permanence threshold required for a bookmark, it stays in the tabs. That is something I hadn’t really considered before, although I was already applying this concept.
