Many macOS users will agree that InDesign feels veery laggy compared to other apps (like Affinity Publisher for example). I really wish you could finally implement a more responsive UI with native macOS UI components instead of scroll views that scroll like it's 1999! :)
Adobe XD is a really good example of what I mean by "responsive" UX on macOS. I understand that XD is much younger than InDesign, but if you don't want to miss out on the next generation of graphic designers, you should really do something about it.

P.S.: I can't speak for the Windows people. Is there a difference in UX between XD and InDesign too?
