[FEATURE] Controller support within games added to the library

[Baggette]

Is your feature request related to a problem? Please describe.
no, its more like a QoL feature

Describe the solution you'd like
when you add a non steam game to your library in most cases steam will handle controller input, for example if I launch this game and it doesn’t support a ps4 controller, if I use steam it has some sort of like compatibility layer which sort of translates the controller’s input into something like an xbox controller.

Thanks for this suggestion. I'm currently working on this, but I think we should first add support for gamepads in general for lazap. Once that has been done, we should somehow develop our own way to emulate a 360 controller to the games, which is what I think you mean by this, since 360 controller translation is usually common in the case you described and most engine API's support it by default (assuming the devs didn't intentionally removed it).

This will be partially/fully developed in 0.7.1 release, depending on how far progress goes. Introducing gamepad compatibility will also open doors for lazap immersive mode (#141).
