Allow to change download location
Allow the Android app to choose where to download files to.
+1 to this. Apps like Google Messenger won't pick up photos in the Join folder within the app's image selector, so if I want to send a picture from my PC, and then text it to a friend, I have to manually move it from Join to Downloads.
Are you a Tasker user by any chance? Tasker can auto-move the image file(s) for you every time one comes in.
I own Tasker but never use it. That is a good idea, but it would still be nice if I could do it from Join.
