Is sorting by Space ID (instead of Space name) definitely your preferred sort?

I would go for Space Name personally.

I can sort of see arguments either way, although I think I'm inclined to names too.

The argument I can imagine for ID is that lower ID spaces are probably often more core / more common, and you probably get sort of used to that order? Maybe?

Obviously they're quite bad if you have 100 spaces, but this should probably be a typeahead at that point.

We could also do something like: default space first, then other spaces in alphabetical order. But that might be a little confusing/weird over just doing something simpler.

Any of these options is better than "alphabetical ID", which is nonsense, of course.
