This may be old news to some, but I just found a very handy trick in BaseCamp 3.2.1.
If you create a Waypoint or Route for testing, or import info that you need to use temporarily, it can be a real PITA to go back into My Collection -- especially a large one -- and find all the bits and pieces to delete them if you don't want them cluttering up your maps and lists.
What I discovered this morning is that if you leave the item selected in the list where it was created (such as Recently Imported), then open up the full Collection, the selected item will be visible in the window and highlighted.
