HI. The Automation Game is editorial;
so it would be useful to add a keyboard shortcut to undo the last action - comes in handy in the engine building department.
In addition, it would be useful to expand the fixture menu to half screen for easy viewing.
Unless I am mistaken there is indeed undo and redo buttons on the fixtures tab. And I am also positive that I have used Ctrl Z in game to undo mistakes in game.
If you’re trying things and don’t want to lose your original tune, for engine or trim, you can use the “hold trim/variant” button, and then you get a comparison between the two.
