The idea is to add a property on game data in order to specify some details about that particular game, such as "lightguns, mouse, keyboard, rumble, 3 or 6 button, analog etc.".

This presents a challenge though: leaving it a plain "string" array for users to specify makes this non standardized for themes to take advantage of, but defining these properties in the app's code is also a significant task requiring plenty of research.

This idea has potential though as it can be help in organizing the user's library more easily, but the implementation of it needs to be better discussed and experimented on before being tackled.
