– Formatted as extended internal memory – dangerous as it can easily damage your OS
– Formatted as removable external storage – safer but not all apps can use it
Im not sure if the apps you mention can use the SD Card as removable storage, since Google changed the way apps can access it. If those apps did not yet implemented the new external storage access API then you will not be able to use the SD Card for them.
DMD2 app on the T865 can write to SD Card when you format it to external storage, that is a safe option that should work.
The buttons you need or not are different from user to user.
We can add option to select what to be visible or not. Most of the layout is originally for tablets where there is plenty of room for everything.
Let me think about how to make this user configurable. For me personally I use most of the buttons and when I ride I like everything accessible with the minimal amount of taps.
Another I will probably add is ability to hide elements when moving. For example, as soon as you start moving hide bottom bar (a bit like the auto lock when moving).
I am not sure i understand what you want.
You are looking for an app that will sync files between your device and the cloud?
Apps like Google Drive / One Drive / DropBox ?
