-Change the title from modrana.py to Modrana or something.
-While not in full screen the lower row of icons (Menu, Zoom in/out) goes below the screen edge.
-Map layer names are variable namish rather than user friendly names (gsat instead of usual Google Satellite), Title is also not proper yet.

Thanks for mock up. Implemented stuffs seems to work fine!

Btw what is the short horizontal line at upper right end?
