Good idea. Will add that. BTW, the flarmcfg that I attached to the last mail 
contains only Unix line separators. In the Flarm Dataport Manual it is 
requested that each line is terminated by 0A0D characters. I changed that in 
the meantime.

Will add a file save dialog.

Ok so I will start to add these additions. As for a license issue: in the 
Flarm Dataport Manual this text is contained:

<!--
Note that this document as well as the interface described with it are 
proprietary and copyright protected. Any non-licensed use, dissemination, 
copying, implementation, reverse engineering or decompilation of the
FLARM data port communication protocol or parts of it is forbidden by law and

not be used without license.
...
Please let us know about your products and designs that use FLARM’s data 
stream.

To be on the safe side I will contact the Flarm developer mailing list and 
anounce our activities.
