Greetings Markus,
Still loving your app. However I have recently noticed that hiding the system status bar in Android 4.1.1 Jelly Bean does not seem to work at all. I know the method is rather abrasive on Android 4.0+. When enabled in Jelly Bean, the Superuser prompt just comes up repeatedly asking for permission no matter how many times you click allow. Since this is more of a hack than feature on Android 4.0+ I've been brainstorming other solutions.
With that in mind, I was wondering if it would be possible flip menu bar 180 degrees and put it by the system bar? This in combination with the
Notebook content relative orientation setting, set to
Flip would make it look like this:
Lecture Notes mock up. I realize this is somewhat awkward because the app would essentially be
upside down but it I think it could be beneficial as it would prevent any accidental hitting of the system bar.
Another solution I thought of (in combination with the
Notebook content relative orientation set to
Flip and an option to have the menu bar completely hidden) would be to allow more customizable options via the toolbox.
Here is a picture depicting what I am referring to.
Thanks again Markus! Your app and your constant development is truly amazing.
EDIT: Sorry for my quick Gimp editing but was merely trying to get my point across

Easier via pictures. Also, I think the 2nd solution would be the better of the two, simply because it adds additional features that others could use even if they don't use this type of layout.
