you should be able to change it externally, does that not work? really
start-audio is designed to be put inside the .fluxus.scm script in your
home directory which gets called automatically on startup, so it usually
only gets called once. I do need to look at that area though, it should
pick up the samplerate and buffer size from the jack server for instance.

no clipboard support - crossplatform clipboard support is possibly the
hardest thing I've ever looked into doing! :) X11 alone is a nightmare.

whats happening with this is that I'm moving fluxus to plt scheme, which
will enable us to use the drscheme IDE for fluxus coding - this supports
all the things you want from a proper programming editor, syntax
highlighting, stepping debugger, graphical profiling - and clipboard
support :)

the current GL editor will still be there, but for smaller scripts and
livecoding.

cheers,
