Perhaps, although Account Settings is going to need a complete overhaul soon, as it has a number of things missing.
I’m also looking forward to the request to be able to temporarily mute folders:
The controls for notifications and for mute could go in the same place. That’s why I’m thinking either a context menu or some sort of clickable icon next to the folder.
Looking at Mailspring again, it may even be a good idea for the folder icon itself to be clickable and have an indicator badge, if that’s possible.
