New user perspective here.
When manually classifying objects in the Dense point cloud, it would be more efficient in some cases to be able to use the polygon tool to make a selection. The free-form select tool is good for some things and probably is great with the use of a stylus, but for mouse use, it is a little inaccurate in many cases requiring multiple selections to select some objects when trying to keep the selection "tight".
Thank you for your consideration.
