One can control whether fractions change their script size and other
features with the FractionBoxOptions.

fraction = Style[(a + b)/c, 
   FractionBoxOptions -> {AllowScriptLevelChange -> False}]; 

Then to write a Text cell with the fraction:
1) Write the text and leave a place for the Inline cell.
2) Put fraction into the Inline cell and evaluate in place.

You can also control text format with the LineIndent and LineSpacing
options.

Presentations used to have an Antialiasing command, but now that Version 6
introduced it as the default standard the shoe is on the other foot and it
has an Aliasing command! Many users might not be aware that Antialiasing can
be turned on and off, not just for an entire graphic but also for individual
primitives. If you are drawing horizontal or vertical lines then
Antialiasing will often cause them to be slightly fuzzy and thick depending
on their exact placement on the screen. By turning Antialiasing off for
these particular lines you can sharpen them up. You will notice that WRI
does not use Antialiasing on Frames and Ticks.

First, one can never tell ahead of time what might emerge in a 
subsequent version!

Second, as to size of typeset fractions: the often unpleasant small size 
is akin to the default behavior the "gold standard" of mathematical 
typesetting, namely, LaTeX. There the size of fractions in in-line math 
automatically shrinks, but if you want to resize it larger, you can 
explicitly do so by inserting a markup command to say to use display 
style, which sets numerator and denominator in normal size -- with the 
result, of course, that the line with such an in-line fraction becomes 
higher than normal and extra inter-line leading has to be introduced 
(automatically), which can lead to unpleasant results.

(So what mechanism would you want to control fraction size, and how 
would you want the inter-line spacing to be handled. (AFAIK, Mathematica 
does not a distinction between typesetting in-line math and display math.)

Third, as to indicating where an error is: perhaps part of the 
difficulty here the very syntax of Mathematica. Syntactical scanning of 
an expression is not such a simple thing. Here I contrast with J or APL, 
where there is a fairly strict left-to-right or right-to-left 
syntactical scanning, so that it is essentially trivial to determine 
where an error occurs.
