Nothing against multi-process models, though I note they're far more common on non-Windows, other than browsers. But why on earth is it necessary?

I wish they'd give it a redesign building it the old fashioned way with the Windows API.

That's good, I guess. But speed isn't my pain point with Teams. The UI is.
