You have the best understanding of [widget] so it would be excellent  
to apply that to tclpd.  Any interest in helping?  I am not good at  
Tcl/Tk, but I think it would be a very useful thing to have in Pd, so  
I am planning on doing what I can.  Now that I have a better grasp of  
Pd's GUI API, I have just started to think about how to make a tclpd  
API.  Federico and I talked briefly about it, maybe he's been  
inspired recently.
