I removed my comments from Openrepos regarding this app, thought it would be better to put them here.

I installed your latest version of BatteryOverlay2 just to see how it looked with an all white ambience, much to my surprise, the overlay didn't show. The app installs without problems and the settings can be played with but still the overlay does not show.

No matter though, I've no further intention of using the app, just wanted to let you know it appears to have problems running.
