Enable editing via ResEdit
I'd love to see Airmail adopt the necessary APIs and tools to support ResEdit for greater UI customization. This would give me the ability to make the app look exactly how I want. This feature would be difficult to implement, as ResEdit was discontinued when OS9 was no longer supported, but with the proper emulation, I'm sure you could get it up and running- perhaps you could even include an OS9 emulator in Airmail itself! I'd love to use AppleWorks again, as I'm sure would everyone else too.
