Feature: Home button on controller can be used in mappings now! This is still in testing, so please give feedback if you run into any issues.
Fix: Remote Play taking over controller input, preventing mappings from working
Fix: digital L2/R2 triggers (such as on the Switch) from permanently leaving L2/R2 depressed
