First query: is it possible to make extra skins available from inside GenoPro in some way? If you do not know about the XML toolkit you would probably not find it.
Second comment: to add these extra features you first have to create a Skins folder in GenoPro by opening the Report Generator and clicking New. This creates the folder and places the basic Customized Report there. It might be better if this was done at installation, or at least the Skins folder was created, for alternatives. This used to happen at installation but has been changed. Was this because it caused confusion? However an empty Skins folder should not do so
