Bring back the old "Hold page" Presentation Mode interface
When using Presentation Mode with AirPlay set as "Mirror Presenter Page," GoodNotes used to hold the displayed tab when going back into the file interface. This was very effective for avoiding distraction for students when looking for a new file to display. It appears that in mid May with no explanation this feature was removed.
Now, when pressing the "back" button to browse files, the AirPlay display now shows the file interface, rather than holding the displayed page frozen.
This feature was critical to how I used GoodNotes in my classroom, and I hope it could be reverted, even is as a toggle feature in Settings.
I imagine others may be surprised when as "back to school" season approaches that this interface was changed. Please upvote if this was important to you as well.
