I know it is possible to have a differnt font for chat and other things. Is it possible to create a UI Mod that will read the fonts in your Interface folders, and let you choose between them, and then change the font on the fly?
since the changes in 1.7 this may actually be possible. I will look into it, although chances are someone else already is. I vaguely remember someone else asking the same question when the SetFont script functions were announced for the 1.7 patch...
