I think a "Back arrow" on the top right to exit the app would be nice for consistency with many other apps and menus. Most of the menus and apps in the Onyx seem to have one. Actually I would prefer it to be a "X" button to indicate it would close the app, but the boox never seems to use that icon.
I know I can close via hardware "back" button, so I defer the decision to you whether this actually makes sense.
