I like it. Seems good to me. Works on Linux. I'm less sure for Mac OS X.
Did the system background color working on linux?
Anyways, the UI needs some more work:
* if "Use system background color" is checked, the associated wxColourPickerCtrl widgets should be disabled * the same for "Use system foreground color" * "Element colour x" doesn't mean anything to our users, the text should be replaced with a better text (for example "SQL words", "Text literals", or something better)
When this is fixed, it'll be applied to the SVN (unless anyone objects).
