I'll think about it, but I'm probably the wrong person to write up the 
process of creating/modifying widgets at this point. But I'd love to see 
Peter write up the process he went through. All I did was add some 
flexibility to the xml parsing (which in LCB ends up working with char 
offsets and is ridiculously ugly, fragile, and error-prone) and allowing 
hex representations of color specifications.

Here's a link to the folder for the LC8.1.3 version - no changes to the 
source required, but the Extension Builder popped up a few extraneous 
windows during the process. I just canceled out of them and the widget 
seems to work.


I had to move it out of my Extensions folder after testing it since 
having both the LC8 and LC9 versions in places messes things up. This 
changing binary format thing is a pain.
