Great Photo is not so great.........

I configured Aperture to use Great Photo as an outside editor. GP opened but the photo from Aperture wasnt there. Apparently no way to get it there. If you do the same with Adobe Photoshop, your photo will open in PS. Not so with Great Photo.
No "Save As," no "Save," no "Close image" feature. The "Preferences" setting has too few options. I guess the only way to save the adjusted photo is to "Export" it.
Sorry I wasted the money. Ill stick with Aperture and Photo Shop. I should have known better.
