After some searching I figured out that I can customize the controls in Kodi by modifying "/recalbox/configs/kodi/input.xml". This is a good start, but this only configures "global" controls. With Kodi you can customize the controls to be dependent on what's going on on the screen. For example the A button would do something different if a full screen video was playing as opposed to navigating a menu. Anyone have any tips or advice how to do this?
