Love the interface and the wealth of data that can be displayed. Two suggestions for additional overlays. Mercator projection with daylight / night shading - civil/nautical/astronomical dusk/dawn levels along horizon - similar to below image as it affects weather.
Other overlay, similar to daylight would be ionospheric levels on a world wide basis. Maritime and HF aircraft communications overlayed with weather could provide a single view display of critical information.
Thank you for your consideration of these additions.
