MCJazzer thanks for understanding.
In fact we are two developers and two people doing part time technical support
Yes, we are very small. We work very hard trying to add features as fast as we can on all three platforms (iOS, Mac and Android).
I try to focus our development resources toward the features that the most people are going to enjoy.

Re: Styles that switch between sub styles between A and B sections.
I chose to not switch at every chorus because frankly it drives me crazy when bands do that.
The groove never settles and it starts becoming predictable instead of a happy variation.
If you listen to some of the masters of this kind of playing like Oscar Peterson they most probably stay in one style for the solos.
That being said, I understand that it's a taste thing and there is one workaround you can use to make the app keep switching at every chorus.
Make sure that there are no repeated sections (you might need to write out repeated sections) then put a big repeat from the first measure to the last one.
Now you can add a text indication at the end of the chart, of how many times you want the song to be repeated for example x4 and then set the player to one chorus.
Since the player believes you are now in the first (or last) chorus it will keep switching styles for all 4 repeats.

Here's an example:
After You've Gone - Henry Creamer
