:+1: - it was mostly about "damn, it _feels_ like there should be a better way".

In this particular case that'd be a bit more awkward, because in the actual game the UI is driven by async fn (the rendering itself is sync, of course, but waiting for input is async, and both happen as a part of the same function).

`spawn_local()` could be a good enough solution for that, though.

Yeah, totally. I have those same feelings. It's hard to fight it because `.lock()` and friends do _feel_ heavy!
