> Combining tabs and bookmarks into one cohesive display, that allows the moving of one to the other
While I haven't used arc and don't have experience how that feature feels, I think the over 20 year old concept of a bookmarks menu, and tabs, as separate things is the best and never needed solving, and any attempt be different is worse than the original (like android firefox and its 'collections'. Why? Or Linux file managers hiding bookmarks different locations that operate differently called "Go", "Places" and actual "Bookmarks" that change through versions and sometimes coexist for some reason so you never know which menu it's going to be this time)
