Love the opened-from tracking for tabs and spatial organization, which reminds me of the Promnesia extension [0] that helps you track when you've been to a page in the past and where you came from.
I think there's a huge untapped potential value for users in historical browsing activity that is just wasted by browsers today (well when they're not busy siphoning it off to advertisers). The standard browser history data and ui is so crap at mapping to your intuition about how to find some tab you had open recently that it's basically useless. It was modeled when the primary navigation in a browser was one window with no tabs and you clicked from site to site literally linearly, and this design has never been updated since. Now I have 2-4 windows, with dozens of tabs each, on 4 computing devices, where windows have been open for times ranging from 2 minutes to 2 months, where on each each tab I may switch to it or move it or close it or open new tabs from it at any time. And all that activity is reduced to a single linear 'history' where the order in which items appear is nonsensical no matter what sort order you use. Real browsing activity is no longer linear, modeling it as linear is hostile to the user.
Knowing that you've seen something before but you can't figure out when or how you got there because it's pointless to trawl through thousands of completely unrelated links in history is despair.
