QuickList Delete button permanently deletes your watchlist with one click. I accidentlly clicked "delete" when I meant to click "detach". Then, poof, if was gone. It took me months to get my watchlist just the way I like it. Now I have to do it all over again. Maybe require a double click such as a warning like, "are you sure you want to delete?" before actually deleting the QuickList on the home page.
