Thanks Juan, this is really great. If folks haven't tried it yet you
should - it does really make a difference (and I'll update a trunk image
soon so that you get the nicer fonts out of the box). About more sizes
- I think the one additional thing I'd wish is a size suitable for
Window titles. It looks odd to have nice fonts in texts and lists (and
the chosen font is great for that) and then not-so-nice fonts for the
Window titles. I tried using the 9pt font for titles but it's just a wee
bit too small.
Other than that: Way to go!
Cheers,
