Stage Manager Isn't Optimized for Mission Control?

Aps aren't optimized for stage manageer driving crazy? Or it's just the general chaos? It's both. The ap thing is a huge piece of it. Apple has these things called a size classes that are basically, here oer the size that you're the sizes your aps can be on an eiepad screen. And they hask developers to essentially build an ap that is each of those sizes so that when you want to use it inside over, you can. Some aps have done that, and some aps have not,. like g male will not let you use it in half screen, for instance, which has always irritated me.
