Make a native and functional PC port
Simpleplanes’s pc version is underwhelming and lacks cohesive support for video settings, hotkey changing, and interface controls that many other games have as a default (the last time I played, for instance, Ctrl-Z was basically broken and arrow keys were practically unusable in the editor. Parts are still controllable through the unintuitive pitch-roll-etc settings instead of just being bindable to a key. Menus that should have been dropdowns just cycled through options instead, which is ok on mobile but horrible on pc. UI scaling is basically nonexistent).
I hope that the devs do these things better in SR2.

In the main menu of SimplePlanes you can customize the controls and bind controls to keys. There's also an option for UI scaling.
