I was able to finally track down one of the reasons why GMMP would not appear as a default music player in a lot of file managers, so that should no longer be an issue.
There wont be any development done this week because of the holidays but i will start back up on Alpha 3 next monday. The crash logs for 2a have been pretty good so i dont see the need to rush out any quick fixes
-Return to playing will no longer reset the library view back to the first tab
-Bypass keyguard for custom lockscreen will now work on Oreo (only when PIN/pattern/password is disabled)
-Fixed playing audio files from file explorer apps on newer version of android
-Fixed issue saving changes after modifying and existing playlist
