Version 1.2.1 adds mappable hotkeys R, F, Z, X, C,V and mouse button #2 (scroll wheel click).
Also added for the first time is a beta channel, where you can see future versions of Minecontrol.
Version 2.0.0a is currently uploaded, offering a refreshed UI. It is currently lacking some major features, namely controller configuration and preference saving, but it does have pre-configured use of the D-pad. You can use these two launch links to switch between the different versions.
Note that at this time, the controller left joystick is permanently bound to W-A-S-D and the controller right joystick will be bound to mouse movements.
