a couple of more notes:
1. adding line breaks _directly_ in the text sample field is not possible, however, I found that creating the sample I want in notepad (line breaks and all) and then pasting that into the field works perfectly
2. for me, the issue with the line breaks only really became evident when trying to print catalogs of dingbat fonts where the character size could be much larger than your average font.
3. a few other feature requests while I'm at it
-placing lines between or boxes around each font in a catalog
-Page # of #
-adjustable font size (this seems to be handled automatically now, behind the scenes
After, investigating A LOT of windows font utilities in the past few weeks, you guys are very close to having the best.
