Thanks a lot! I am surprised how fast devs are picking this up. Phasex,

Hydrogen, Rakarrack ... great work already :)

Next thing what would be good to have imo is a good software mixer with

JackSession support. Unfortunately non-mixer is not a good candidate

afaik, cause it changes port names. I don't know if Fons is still busy

with his mixer and if he has explored and made up his mind about the

actual implementation of the JackSession API already. Otherwise Jack

Audio Mixer might be a good candidate maybe: http://home.gna.org/jackmixer/

Qjackctl 0.3.8 has the possibility to use 'versioning', it makes backups

of the old folder when you overwrite it.

I wonder how much space those folders take in general and if that space

is really a problem normally.

Would be good if Torben (and/ or Rui) could comment on this.
