Mailsuite 2020 for Big Sur only has entered Beta. I’m so tired of wandering the desert looking for mail clients. I think I’m about to go back to standard Mail.app and augment it the way I want.
I’m betting on Big Sur being a internal cleanup of code and UI refresh and subsequent major releases will focus on the UX more and if I’m a betting man I think Shortcuts.app finally hits the Mac next WWDC. When Shortcuts hits the Mac I’m pretty sure that it’ll eliminate about 60 % of the hassles with integration that we see now.
