Maybe you already know this, but if you just want to change the font size of track names (to a smaller size only), go to Preferences > File > Initialization File, and enter "TVLargeStripNames" in [Option] and "0" in [Value] and click [Set]. For bold font, it's "TVBoldStripNames" and "1".
Actually, I was not aware of that, but I have never really thought about changing the strip names. I would like to be able to make the fonts larger. What I would really like to change is the size of the values associated with controls and metering. Having a larger tooltip or popup show the value while making changes would work.
