Some additional useful apps/app combinations for the mars:
Gesture Control:
https://play.google.com/store/apps/d...esture.control
Allows you to "create" an invisible (layout > hide bar) bar on the bottom end of the ereader, that does different actions if you move it. Moves to the left and right are the most reliable. I have it set up to trigger "home" when moved left (and left while holding), and to trigger the notification tray when moved right (only works in the default launcher (in most full screen apps it pulls the notification tray "in the background" (so while the notification bar, and tray are still hidden) so that gesture only has specific uses - more on that later).
This enables you to exit all apps - back to the launcher, without having to fiddle your way into pulling down the notification bar and hitting home. So its more reliable and quicker. It doesnt conflict with the use of Comixology or Perfect Viewer either - so its actually a decent solution.
Notification Launcher
https://play.google.com/store/apps/d...pyware.quickli
To pin a few app shortcuts onto your notification tray. I use this, because I actually like the default launcher so I won't replace it - but then you also benefit from having some app shortcuts always available.
This is also the reason I have Gesture control set to pull the notification tray, its easier access to the way I launch most apps.
Force Rotation:
https://play.google.com/store/apps/d...force.rotation
I've found to be a reliable way to have the screen rotated based on which app gets launched. It works in the background and doesnt need you to take any action, once you've set it.
All those apps have to be allowed to run in the background and to be launched on boot. (User Settings/Power Management/Application startup manager).
