Sorry, this isn't something that we plan to do. Screen locking is an operating system feature, not something that individual apps would tend to implement. As for preventing your device from going to sleep, we already do that.
If you inadvertently knock the screen and scroll the map, it will scroll back again after a few seconds.
Most people seem happy with the way things currently work which is why changing things is not currently on our radar.

I don't want to get into some kind of semantic argument. I didn't say "retail". A computer locked into what is commonly called "kiosk" mode runs one application or provides a certain restricted set of functionality. 

I want my Nexus 7 Android tablet to only run Skydemon while I am flying. The other day I didn't touch the screen for 20mins and I had bring SkyDemon to the foreground again. The tablet popped up mail and FB and Ebay notifications while I was flying. I do not want that.

It is easy for SykDemon company to engineer the SkyDemon app so that it works how I wish. Those arguing against it would not be harmed by the new features, and soon enough they will love it.

Now with Lollipop it is easier still. 

I have had to lock screen rotate on my Nexus 7 Android 4.4 but this effects all apps. Very annoying. And I can only lock in portrait, I would like landscape option. Please implement this as a SD feature/option.
