[LAU] like "qjackctl", but trimmed of all fat

Hi Aaron!
   A few notes on your mail: How do you use jack_lsp? Which options do you use? 
jack_lsp is capable of listing port properties and connections.
   About audio and MIDI: JACK has both audio and MIDI ports. If you want your 
tool to be intelligent, you might consider it. I think with options -P lists 
properties and with -t you can specify to only display a certain type of ports 
(audio/midi I suppose).
   How much checking do you do after all? And how much checking would you 
eventually be willing to use? (not connecting audio and midi ports, not 
connecting output to output...)
   I think the easiest way to have a kind of audio and midi tab, you can use 
different print/list commands. E.g.: l for listing all ports (probably with a 
hint after each name or divided in sections. Then you could have specialised 
listing commands la lm. I don't know: How exactly is qjackctl organised? Does 
it have seperate tabs for ALSA midi, jackaudio and jackmidi or only alsa and 
jack? Depends on how you might wish to seperate.
   The other main idea is of course to use different modes. In that case you 
might take these modes up in the prompt:
jackctl (audio 'h' for help)> m
jackctl (midi 'h' for help)>
   By the way: Thanks for the hint with l. I've just seen it a minute before I 
read your mail, since I saw a complete output from jackctl. Still it's very 
good to know.
   Kindly yours
             Julien
