Awesome! I was not aware that the source was available for changes.
The idea is to make the interface driven by joystick instead of mouse and keyboard; so if you are using something like a portable console, like a gameboy, you can use Octamed just by using the joypad and the buttons.
I tried with mouse emulation but it is not exactly simple to do, and workflow really get affected. Hope this is possible to consider, otherwise I will check Arexx
