I'm sorry you can't find enough time to work on NeoForce controls :(
It's a really really good library for making a GUI in XNA !!!
Thanks for giving us the sources of the XNA 4 version on codeplex :)
Could you give us the latest XNA 3.1 version sources ??? I have a bug (can't enter any @ symbol in any textbox controls :()
It would be so nice if you could give us the whole sources...
Hope you'll be ok
