Customization ideas
Animated profile backgrounds of your main You know how ultimate skins have a animated background in your profile? Why not make that for most champs cause a lot of champs have animation from log in screens. Also with it add a option to choose your main champion and it will always be in your profile background. (IDK it might downgrade ultimate skins)
((Ability and Item tray skins)) You know that tray with your items and abilities in it? It should have some skins for it to make it look different also minimap.
((Adjust color for client)). This one is pretty basic and kinda stupid but. Maybe some people want to change the color of the client?
((Change size of client)). In the legacy client you could change the size of client freely like web browser. And it would adjust to that size showing more or less stuff on screen. But i think the new client will already get this.
((Animation for Honor Crest)). It would be cool if it would be animated or even become a sort of emote at level 5.
Well i'm just thinking out loud really. All of this is just some concepts and stuff IDK '~' lol
