Here is what I want. At the bottom of M96 there is a rocker switch for the volume selection. It's pretty useless to me most of the time and sits there gathering dust.
I would like to use it for turning the scribble mode in
Onyx Neo Reader on/off (say, volume up) and for turning the eraser mode on/off (volume down), or whatever other function I feel the need for.
I've never seen any mention of such feature on this forum before (the search doesn't show much) so it may be that this belongs to the feature request section but asking doesn't hurt.
Also, I would probably not need that feature if one could customise the status bar in the software. But that's most definitely is a feature request as I can't see any way to do it. Seems like it's time to learn writing Android apps...
