I was researching a wrist watch for myself the past few days but I want/need an (apparently) very niche and rare complication: A timer. You'd think this should be a fairly basic feature to put into a technologically advanced watch but apparently not.

I've found that bookmarks don't really work for me because they're A. clunky to manage and B. don't retain context. I often branch off from one tab to multiple others or open a new tab next to one on the sub-topic I'm researching. It's hard to describe but it's a workflow I've gotten rather used to.
I'm aware of tree-style-tabs but haven't found the motivation to set it up yet and am a little unsure whether I want to let an add-on handle functionality so core to the browser.
