I use "bookmark all tabs" to temporarily save a group of pages I'm using. If I previously bookmarked one of these pages, the old bookmark gets deleted without warning. I don't want this behavior, it STINKS (to put it nicely) that there is no option to keep the previous bookmark. I want the bookmark that I carefully saved into a specific folder to remain so that I can delete my temporary folder without needing to move each of the bookmarks back to it's original folder. I guess you have a control freak who knows what is best for everyone working on your bookmark functionality.
