Bump for god’s sake. Been yearning this since day one. Relevant to this would be cycle-through pre-defined view presets. I could group my pattern editor, instrumen/sample editor, mixing and whatnot purpose screens under same key. No need to remember gazillion (okay, eight) of them, just press, press again and joy.
e_now thinking of it, could be mapped with only the feature of multiple-hit hotkeys. So this is one example of use.
As I would be using this for grouping similar shortcuts, I would have no trouble for this to be done so that first hit already executes first command, and second hit executes the one mapped for double press, third executes the third and so on.
This way there would not be any need for waitig new keypress which would make usage sluggish. All stages would also be undoable in reverse chronological order.
