When you drag resources or collections to the "plus these resources" or "minus these resources" areas, they go in all higgledy piggledy, whatever over you put them in there. It would be nice if they sorted alphabetically, so that it would be easier to see if you'd included everything you intended to.
For example, I suggested a method for creating a collection containing just those books that are not in any other collection when a forum user was looking for a way to find all those books. Drag each of your other collections into the "minus" area of a new "Books Not In Any Collection" collection. But if you then create more new collections, they will not be included automatically, so you've got to remember to drag them in as well, when you create them. Otherwise it's a mess, and hard to find which collections you've remembered to include and which you've forgotten. Especially if you've got lots of collections.
It would also be nicer and tidier for book titles to be listed in alphabetical order in those sections, even if they aren't complicated by having nested collections.
So, please consider it...
