AppImage. Uncompressed installation?

[ignaciogros]

We need a solution to install iDevices easily. Suggestions:

• Uncompressed installation (notice that keeping apps compressed all the time is one of the objectives of AppImage: https://askubuntu.com/questions/774490/what-is-an-appimage-how-do-i-install-it)
• Read iDevices from the user's folder

We'll provide instructions to the testers if they need them.
