Thank you for providing a extensive config mastercoms.

The .deb package for dpkg (7.0.0-a4-amd64) puts everything in /opt/mastercomfig correctly but, the default permissions are root:root 700. After I fixed that I noticed a .desktop file wasn't generated in /usr or ~/xyz/.local/share/applications, essentially no menu listing in whatever DE.

Again thanks for making a updated config and the app looks promising.
