[PD-dev] seeking advice on Pd gui overhaul

[João Pais]

I'm not a coder, but I could also give a sugestion, which I haven't tried  
myself for lack of time: how about circumventing tcl/tk, by writing your  
gui in gem? There was once a report that it's much faster - I can only say  
it does if you're using data structures inside a gop.
