Wish List item:
I really like the addition of the free-form selection tool in 0.9x, but it would be very nice (for aerial orthos and DEMS to be able to import shapes (kmz or .shp) to constrain processing and/or output.
Ideally I would like to be able to constrain both point cloud processing/output and mesh generation with a shape file, but kmz would be a good second. I don't know how much processing time this would save, but for me it would make it a lot easier to remove areas of dense complex vegetation that eat up my polygon count. Clipping the dense cloud manually isn't practical because the 400-800 million points bog down my system too much.
