Quality of life, but I think it will help.

peppy has already improved how collections work by letting us quickly adding whole sets to a collection. This is useful for categorizing but if you need to undo an error you would have to constantly reclick and remove all the difficulties in the collection filter, and since the difficulty is removed from the collection, you're taken out of the collection and have to click on the collection and a different difficulty again.
On the other hand, if you use show all you are unable to tell which difficulty is in which collection quickly.
A way to resolve this is to have a "Remove Set from Collection" button similar to how there's an "Add Set to Collection" button, or instead make a toggle to change between adding difficulties and sets to removing difficulties and sets.
So since I'm terribad at writing, I don't know how to end this.
tl;dr - read the title
conclusion - please just do something
