aye, it's one of the missing features in my opinion, some people use resteem to 'pin' something to their page and others use normal browser bookmarks, usually the more things you want to keep track of the better it is to lean toward bookmarking. In chrome for example I have a steemit bookmark folder and inside it has other folders for categories, just like file system on computer, so you can start sorting over time after the main folder gets a bit cluttered with things (assuming you bookmark as much as I do), hope that helps :)
