When switching to a commentary or dictionary, the highlighting bar remains active. I seldom notice this, and begin tapping on the screen, thus highlighting Eze_6:3, Eze_11:8 or whatever it is I'm looking into.

Then I have to go back and select white highlighting and repeat the action to erase the yellow. And then I kick myself, and turn off the highlighting bar.

This is rather annoying to me and it would be nice if you could have it allow the option of automatically disabling highlighting when entering commentaries and such.
