What, me vent? I could show you venting, but I won't.

The real issue here is why this design flaw has persisted from version 
3.0 to version 5.0. It is clearly an example of sheer corner-cutting. 
There is no typographical rationale whatsoever for treating numerators 
and denominators of fractions the same way as subscripts and 

For example, what if I want to have ScriptSizeMultipliers->1 in a 
fraction that contains subexpressions with superscripts? Then the 
superscripts are the same size as the bases to which they are attached, 
and the whole thing looks silly -- thus I have go in and do a lot of 
meticulous tweaking.

Again, I could be missing something and have wasted countless hours in 
trying to make many hundreds of pages worthy of publication. But maybe 
it's my own fault for dreaming that I could approach TeX-like quality 
with Mathematica.
