Rofl, carry over from my programming days. Customers always liked to keep up to date with what is happening whether its bad news or good news
And yeah, I made a brief mention of adding an option to change the font size but not implemented anything like that yet.
Edit:
Well looking at WatchFrame.xml it looks like it should be no problem implementing a font change to both the title and the individual text lines. I'll play with it the next opportunity I get. And I think for simplicity sake I will not make the display counts configurable and just have it set them to higher numbers reflecting the fact that with a scrolling frame size is no limit.
Also, I have tried to make the defaults the same as the Blizz settings so people that just want the movability won't need to do anything and those that want to change stuff can.
