Often, I have to updated bookmarks. So I select one, work on it and updated it. However, when there are many bookmarks I sometimes loose track which one I wanted to update. As much work is flowing into setting up bookmarks, updating the wrong one can destroy quite some working time.
So I propose to show the last bookmark which was selected in the bookmark panel. It would also be nice if the last selected bookmark could be updated directly without searching for it in the bookmark list (it would perhaps be best to combine the functionality of showing and updating. The last selected bookmark could eg. have all the controls a "normal" bookmark has)
