My memory isn't good enough to make "likely" work out here, so that wouldn't be a good fit for me. Right now it's more about "will I use this soon enough", and of course that changes depending on how much time you've got available anyway. And when that happens, I file them away on pinboard or discard them. It does work, but better integration and UX would improve things. And you might got that wrong: I don't want to assign priorities to tabs and/or bookmarks, I just regard both as being in different "priority" buckets, and maybe finer-grained distinction and ease of moving things back and forth would be a good approach. (Never mind: "all the time visible"? Not in my tab tree ;) )
