I've downloaded and installed version 7-RC2 on my Samsung Galaxy S4 Active and made a short test. Everything ran smoothly and even the support for OpenAndroMaps worked.
But I observed a critical bug (for my usage of the app): When managing waypoints, tracks or routes the folder selection list was nearly empty - it only contained the entry "---" and all my items were listed in this one folder. A quick check with version 6.5.10 confirmed that everything is still sorted into approx. 30 folders.
I would appreciate if you can fix this bug before releasing.
P.S.: I use Oruxmaps for a couple of years now for hiking and bike-riding tours. I cannot imagine to start an activity without having your great app activated!
the beta version is a different app than the GP version.
When the GP version will be updated, youi should see your folders.
