I experience selecting a soundfont in the eigenbrowser sometimes as a bit cumbersome, even more when I add my own soundfonts and AU's.
here are some modest proposals fr improvement (unless I've missed something):
1 - it would be very helpful to have some structured search path, like a hierarchy or a tree (i.e. plucked instruments - guitar - electrivc guitar - stratocaster with fx)) ;
2 it would speed up my search if you'd always come back to the place in a list where you left it the last time
By the way, Stage is great and very helpful for quickly setting all Tau parameters!
