peter Thank you Peter for your answer!
1) Regarding this one this is the way I am using it currently and it works. I figured to me mention that as it might be useful and more straight forward. Saving this also would be great as you have to press the next region to and be on top of it manually controlling the regions. Maybe it could be save so it atomically everytime it skips a region or goes from the first to the second.
3) Done that already as per the instructions above and I think it will serve me well.
6) I updated to 3.7 just now and now this behavior is gone. Now it follows the speed of my finger as expected.
7) That's great. I only use the player side of the app and not the lyrics so moving in and out the sub-menu "inside" the playing song, in the small iphone screen, to find the cross fade and loop is making it less easy to navigate.
