Might be a good idea to explain for newcomers how/what 12 bar blues is. It's a shame that the forum is getting clogged up with multiple charts with the only difference being the key.
Just wondering whether the multiple 12 bar blues and rock and roll etc that are listed could be lumped together and put under one heading. Seems mad to have so many listings for the same chord progressions.
Yes it times out in full screen mode. Quite annoying as the maximum default time out is 10 minutes. I keep a security pattern enabled so that there is a level of protection if somebody steals the tablet but it's a faff to re draw the pattern each time the screen times out. I have reported it...
Unfortunately I have almost the opposite problem on my samsung tab s4. The screen turns off and I have to redraw my security pattern to get it back on after a few minutes of not using. the only option is to set the screen so that it never times out.
