Please make app more useful

I am excited about accessing on my phone/tablet scores that I am uploading in my account, but right now it is not useful. There is no way to make folders or classify or even just show the list in an alphabetical order. Can't even play the synced audio.

The other option would be to use the songbook, it offers to sort alphabetically, but the only option to transfer files is to open them one by one and it is not very straightforward. No way to open a folder, or open at all from inside the app...

pleeeeease work on the app, I am looking for reasons to pay my pro membership :)
