If you still use A2DP I've got a good news for you. I just posted an 1.3 update which removes Quattro advertisements. They didn't work anyway, since Quattro were purchased by Apple. This also removes annoying CoreLocation warning and white rectangle at the bottom of the main form.
Regarding future development and USB Drive. I still do not have any time to respond to suport enquiries and have to warn anyone who will try to use that this application that it was development on 2.x.x firmware and probably have issues on modern devices.
If anyone have connection problem to apt.dmytro.me please drop me e-mail, I am keep an eye on the server, but sometimes it fails.
