Terje,
Maybe this has already been discussed or mentioned, but I wanted to keep
the previous style CinGG package desktop integration with an app
launcher icon. To add this I used the "alacarte" Menu editor for Gnome
and utilized the previous installed icon /usr/share/pixmap/cinx.svg.
Thanks for passing this information along.  We do have the following in the manual, but if I remember to do so, I will add your suggestion method also.

or create a convenient desktop icon with a link to the run action:
1. right-click on the appimage file
2. Properties
3. Application Tab
4. Command:

         /path/to/appimage/./CinGG-yyyymmdd.AppImage
5. OK
