This sounds like it would require a whole lot of coding to get this done 
properly. And it's only of use to you if it's done properly, otherwise 
you'll turn it off after two uses and never look at it again.

Also, this is something that would only work in languages where the 
indentation is defined by brackets or something. And then only for people 
with the same coding style.

Perhaps I'm a bit biased, because I mostly code in python where it simply 
is not possible to have syntax-aware indentation. (Because the indentation 
*is* syntax).

There already is a feature for this: when you move over a parens/brace/etc, 
the matching one lights up briefly.

As stated before: these are almost all user contributed. If you don't like 
the way it looks, get your hands dirty and edit the syntax file...

And before you ask: A syntax highlighting configuration editor/preferences 
window is already on the list of requested features ;-)
