The bookmark menu supports the same hierarchical organization, and since you're pretty much using so many tabs as bookmarks anyway, I don't see much of a distinction. Deleting bookmarks is a bit more fiddly than closing tabs, but in my mind that is a good thing as I find myself accidentally closing tabs all the time. And I bet the "Close Other Tabs" option probably scares the crap out of you
Tabs are supposed to be short-lived, ephemeral things. Bookmarks have the functionality you want
I think you are kind of rude both in that you suggest you absolutely know better than me, and also in how you present your opinions.
I suggest you take a step back and reconsider both:
- computers as bicycles for the mind. If it can do so much for me, think what you could achieve!
- how you interact with others.
PS: no, "close other tabs" doesn't scare me. If I have to close down something I don't feel I have finished yet I can select that subtree and export it to the clipboard as a nested markdown list which I paste into Joplin where it is searchable.
Also if I accidentally close down something I can just press ctrl - shift - t the required number of times, alternatively ctrl - shift - n if a whole window has been closed.
At least with the work I do it isn't alway obvious what is going to be useful or not. But while I don't have a photographic memory (quite the contrary) I'm often able to figure out approximately where to look and also able to find it there.
I'd even recommend you try it. If it works for a simple farmer turned engineer like me, think what it could do for a smart person like you! ;-)
