We've made some help videos that might be helpful to you. The entire video playlist is here:
All of our help videos so far are using the iPad interface, and we might need to make some videos that are specific to the iPhone interface. But the videos "25. Saving Presets with H9 Control on iPad" and "26. Organizing Presets using Lists" still give a good explanation of the available functionality, even though the layout might differ somewhat on the iPhone.
There was a forum post yesterday from a user who was confused about how to transfer a preset list from an iPhone to his H9. If you want to use the preset list functionality for organizing your presets and are having trouble navigating it, the explanation I gave there might be helpful.
