I run VarAC with different radios and different computers. I point all instances of VarAC to a common log file located on Dropbox. That way, I have only one log regardless of the radio or computer.
It would be nice to have the ability to specify the directory for the VarAC_traffic file. That way, I could also locate it in a common Dropbox directory that could be accessed from all instances of VarAC. I would then be able to view the common Callsign history from all computers.
Since the radios, audio ports, and CAT serial ports are different, I can't just put the VarAC directory on Dropbox and use the same files for everything.
I suppose the same request would apply to other files such as VarAC_frequencies.conf.
One approach would be to enable selection of a specific VarAC.ini file, i.e. have more than one VarAC.ini file.
