I'll look into making delete function that way. There are many hotkeys I'd like to add as well.
After recording a sequence, looking at it in the editor results in many gray input nodes. You have to squint to find the ones that have checkmarks in the buttons.
Instead, each instance of the A button should be green by default, B should be red, X blue, Y yellow, and so on, for all of the buttons, to make them easier to differentiate from the directional inputs when making adjustments.
