This looks awesome! Wonder if something like this could be turned into a generalized optimization engine of sorts? Ie if the problem could be generalized for a set of available movement commands relative to used commands, you could apply it to any underlying platform.

Which is to say, i'd love to see this in Helix. I also toy with custom editors, and observability of available commands is high priority for me, a generalized solution here would be an elegant solve for that. It would also adapt to new features nicely.
