Just bought Joystick Mapper and Joystick Show.
Works great! (except for some incompatibility with Steelseries Nimbus which I'll describe in another thread.)
My (small?) feature request is to be able to add textual description to each binding.
After creating a dozen of bindings I find it a bit confusing to remember their purpose.
I think it would be much more easier to understand presets (and then modify cloned presets for another game or controller)
if it was possible to add "Action description" to each binding,
For example binding "Button 1" -> "Keyboard Space" could have a description "Jump"
