Would be great if I could see my ground control points(in some other color) along with the photo locations. And have them always above if you open the photo tile.

Thanks @gsmercier ! This has been brought up a few times (see the related issue: DroneDB/DroneDB#145) so it's definitely on the road map to be implemented.

What format do you use for your GCPs? Can you share some example files?

When I use your GCPeditor PRO I just bring them in like this and tell it the epsg code for the data (typ for me is 2254) . . .
