For usability and improved UX design, I would suggest changing the page order in portrait mode.
There are 3 pages:
- me reel
- me selection
- group masters
The me selection is a setting that is normally done only once and never touched again.
On the other side, me reel and group masters are used a lot.
In a live show, you will mostly use the me reel, but sometimes you want to adjust your grouped channels quickly for more control.
In these cases, you always have to swipe two times to the right and again two times to the left to get back – you always need to skip over the me selection page, you'll probably never need.
That's why I would suggest changing the page order like it is visible in the mock-up:
The me reel should stay the main page (for example on app start).
Swiping/scrolling to the left shows the me settings (because also the me level indicator on the me reel page is on the left).
Swiping/scrolling to the right shows the group masters (because also the band level indicator on the me reel page is on the right).
I hope you share my opinion and the developers find some time to implement this for the next app version.
