I'd suggest to have full printing capabilities built-in.
I'd love to have on board dialog for direct output to pdf, to system printer or to image file
It could boast a handfull of useful settings such as:
Resolution, scale, position on sheet, rotation, coordinate grid superimposition, scale bar, GCP on/off, etc.
Also print as point cloud with some options for handling point rendering and size would be just great. Dense point cloud printing for small scales sometimes yields to nice true orthos much better than those out from mesh-based orthorectification.
