Points for xsel integration. Information management is frustrating for me since I context shift between clients, day to day tasks, familial obligations & most of this is mostly around the browser. Eventually I suffer from tab overflow, with Chrome taking 28 of my 32 GB of RAM. OneTab autosuspends some of them, but if you write something to grab from Chrome open tabs, clustering by "time opened" (usually I'll open 3 or 4 tabs of, say, resistor spec sheets or something -- time locality is generally correlated with project for me), and the option of annotation (similar to how git does it, first line = title; anything lengthier for more elaborate stuff) and my lord would you have made my life significantly easier. If you add interop with TaskWarrior and/or emacs org-mode you'll almost certainly have a hit.
