My workaround for this issue is to put Mail app in its own dedicated Space/Desktop. Then it only comes to the front in its own Space, not in the Space I'm normally using.
I've switched back to a new MacBook, temporarily due to COVID as it was easy to purchase from Apple and it was an emergency.
I used OS X fulltime 2006-11. I'm surprised how buggy Catalina is, including Mail.app. I have had serious firmware issues too, such as needing to reset my SMC very frequently because my USB C stops charging the machine every other day. Apple is clearly, sadly, neglecting mac OS.
Surprisingly, I haven't disliked butterfly keys as much as I thought I would do. I can type extremely fast. I do prefer their scissor keys, though, which are really good and low latency [1].
Yes, it's new and it's fairly decent. I love mechanical keyboards (especially those with ALPS and TOPRE switches), but I realize low travel means I type much faster and it doesn't tire my fingers.
IMHO the scissor keys in the Magic Keyboard are really good because they strike a perfect compromise in terms of depth, comfort and speed. Also the board is really low latency. Not sure what tricks Apple has played with the firmware in those keyboards.
