I want another way to edit and view my collections

[CRS]

I want to make sure my games are sorted correctly. Small problem: I have 100+ games and I don't want to right click every single one to double check they're in the right collection. I have a collection for every genre, and managing my games is a pain in the butt sometimes. If there was a menu that allowed me to organize my games by collection better, that'd be fantastic.

Here are the issues I face with organizing my games:

• Games being in more than one collection
  
• Adding and Removing games from my collections
  
• Scrolling through collections

Going more into detail, one main issue is having to right click the game and scroll through my collections till I find the one I need.
