Sorry guys, as this was my first mod, I made a very basic mistake: I forgot to test it without adding the mod UI. This caused me to miss the fact that the first version didn't have auto-loading enabled. This issue has been fixed in version 1.1; now, the game function will continue to work as long as the mod is activated.
Advanced Pedal Button Input v1.2
Smoother, more progressive clutch, throttle and brake control for digital inputs.
