The Mail app built into macOS isn't the nicest thing in the world, the UI looks dated and Outlook is a much better alternative (for me at least).
The problem that I am facing is that I need the macOS Mail app to start at login and be running in the background due to the way AltStore works. With Outlook also open, I have two Mail apps open, thus crowding my dock.
Is there a way to move the macOS Mail app away from the dock to the menu bar? Or in general, is there a way to move any app from the dock to the menu bar?
I use an app called Hidden Bar to collapse and hide some of the menu bar icons, with that, I will be able to completely remove the macOS mail app from my sights, even though it's still running in the background.
