Good afternoon,
I was looking in to app support ideas, and it would be really nice to add mail support (ie adding external storage to the outlook app(windows) and mail app (IOS). I’m not sure how much work it would be, but it would really help with adding attachments and such.
BTW great app, I paid the money and it was well spent 
I doubt that outlook app (win) and apple mail (iOS) are open source and do you know if you can contribute your own apps or plugins for these apps?
Or find a different mail app for mobile devices where you can add this…
I believe it’s a developer choose as to wether or not they choose to support the Apple API for the mail app, I don’t think it has to do with the mail app or outlook app themselves.
