Wouldn't it be cool if there was a way to organize/personalize your champion selection screen?
The way I picture it would be, a title on the left hand side, followed by the champions that you can drag into slots that go across the screen horizontally.
Maybe have a row for the assassins you are good at playing, a row for tanky top laners, a row for the current "meta" champs?
I think something like this would add a lot of clarity to the game, which is one thing riot has explained is very important to their game's design. Instead of encountering a mess of champions when you see the screen, suddenly you have several organized lists that allow you to better visualize what kind of gamestyle you want to play in each individual game.
