* bug fix: for mono capture jack audio interface Jamulus complains it cannot make connections (Ticket #137)
TODO implement panning for channels (Ticket #52, #145)
TODO support CoreAudio aggregated devices
TODO support internationalization
TODO standard style: meter bar gets smaller sometimes if board is full and fader text is short
TODO implement panning for channels (Ticket #52, #145)
TODO sometimes I cannot see the central server in the server list
TODO server: warning if Central server selected but OS location is different (e.g. US) -> warning in GUI and command line
