I wish I could publish Trebuchet++, but it is based on a copyrighted MS font. Maybe I will contact them to see if they could give their blessing to this "derived work".
In the meantime, if you or anyone reading wants to have a look at it, my email is in my profile and I can send you a copy "on the sly". :-)
I have a couple of other improvements in mind. One is to add a bit of spacing inside parentheses, curly braces, and square brackets, but I'm pretty happy with the font as it is so far.
