Hello!
Love the app, been using it for a few years! I just wanted to make a suggestion for a feature where you can turn the pages with the volume buttons.
A few apps I use primarily for .epubs has this option to turn the page whenever you press the volume buttons, which is a really comfortable and tactile feature (this doesn’t stop the volume from changing though), and I would love if this was an option in Panels too.
That’s all, thank you, and looking forward to Panels 4!
