I tried lash_panel with hydrogen and muse.
Indeed this looks like a nice way of handling things.
I noticed muse (muse 2 beta) says something about jack didn't start, but 
he did.
And it won't close by lash_panel.

So are that the issues at the moment?

I also noticed that programs like qsynth and zynaddsubfx don't seem to 
do lash.
