Edge-to-edge mode bug

In newer Android versions, the app extends over the system status bar at the top and the system buttons at the bottom. The system buttons get the clicks and thus disable e.g. the OK and Cancel buttons in the grid config dialog.

This bug is in obelisk and we've filed a ticket against them (link?). We could help them by writing a minimal demo of the bug.

As a temporary fix to make the app usable we could just add empty space at the top and bottom of the app, but this would rightly invite ridicule.

Until obsidian fix this, we should not encourage people to test the beta.
