I'm currently rewriting the settings, since I noticed that there is a lot of crossed out text in the current SettingsActivity, using Fragments. While I'm at that, I thought, I could also merge the stuff from my fork, that basically just removes all UI and exports everything regularily, to unify that. My proposal for the settings structure:
Subdirectory structure for albums
Subdirectory structure for playlists
Maximum artwork size
Enable automatic export (Checkbox)
Require Unmetered Network
About this feature (link to a blog post)
Project Homepage (I'll probably create something for this too, since the original dev seems to have suspended his work on this project)
Made some progress, setting the paths does work now, but there still is a lot of work to do, because @Arcus92 did some things in a way that is not easily compatible with the new PreferenceFragment stuff, so most of the pref code needs to be rewritten. I'll commit and push, once the rest of the preferences work again.
The automated export requires API 21 (scheduling is done with jobs and the ExportAllService expects DocumentFiles), so I'll have to figure out how to hide that on KitKat and lower..
