Hi Stuart

May I refer you to <http://wiki.tcl.tk/1304> - this is a wiki which 
documents various web-based tck/Tk tutorials :)
It shouldn't be too hard to add a save/restore function - tcl uses 
strings for every variable and has pretty reasonable I/O functions for 
those strings.  A bigger question is where the config should go.  
Halscope drops a .scope_cfg in any directory from which it was run (I'm 
not quite sure what it does when you run it from AXIS or what the 
"current directory" is when you run EMC from an icon/menu.)  I don't 
know if you'd want halshow to do the same thing.

Another option would be to make a pyvcp panel and a hal file to load it 
and make the necessary connections.  I don't think there's much that can 
be seen by halshow that can't be seen by pyvcp.  Doing a vcp panel would 
also allow you to group things as you like, for instance encoder counts 
and limit switch inputs can be placed in a box for each axis/joint.
