In mobile I am often changing my view settings. As it stands, the one's I use the least are the ones up top, the one's I use most scattered throughout.
I suggest rearranging the settings so that Bible text only and Show notes are at the top along with Scroll view and Max Columns.In my experience these are the one's being changed most often and would benefit from being in a more prominent position.
The default fonts settings are at the top - which I imagine are set once by the user and never touched again, margins and text size as well.
