This is an ok organizational tool for, like, a sitting. But for some reason every time I leave and come back to my computer after a day or two the headings I've set up for each open window just disappear. I have 4 windows with multiple tabs open in each, grouped by the different things I'm using those tabs for. I want to be able to easily and quickly go to the right window for what I want to do, but I always have to start by re-naming and color coding everything because it just... loses those settings after a while. It's annoying enough that I might look for a different add-on for this eventually.
