Would be nice to be able to save an attachment instead of only being able to open it. For example, I often set out a hiking route on my laptop, then email myself a .gpx for opening on my phone. When I tap the .gpx attachment in the email app, I get the choice to open it, but only two applications are shown: notes and documents.
I want to save the .gpx so I can open it with pure maps. I now have to start the android k9 mail app to be able to save the attachment.
