Major Description
Please add JEdit Syntax:
http://sourceforge.net/projects/jedit-syntax
to all TextAreas that display code (SQL, or other syntaxed text).
This library is very small, lightweight (it's not the entire JEdit but an old and simple syntax hightligher).
The inclusion is very simple(just replace TextArea with JEditArea) but the effect is spectaculous:
everytime I integrated this library the users were euphoric 
- despite the fact that my work was little (just a code line).
Please not that the library is under MIT license so it should be no compatibility problem.
After integrating this library it would make sense to take new screenshots for the documentation cause they'll look much better .
