The world would be so much nicer if the syntax highlighter's colors were reversed or changed. Keywords should be blue and identifiers should be black. library functions should be teal. Maybe read colors from the settings file.

Currently I have a light theme and a dark theme. But I will probably add support for gedit themes as they are very simple.
