Did you build some kind of component tree diffing for the reactive UI, like React? Or data binding?
And how did you design the async parts, given that VBA doesn't have first-class functions? Classes and interfaces? Or nested event loops?

I did some async stuff in VBA recently (with events) and it was a bit of a mess, which I'd like to clean up if possible. VBA has classes but not anonymous classes, and not anonymous functions either, so you can't easily do callbacks. And the error handling mechanism is not great.
