Bitbucket user srean complained on the Google Group about the white background in bitbucket’s code view. I agree — a black background is much better for viewing code, and the gray highlighted text is almost invisible against white.
I whipped up a greasemonkey script to correct this situation. It makes the background color of the highlight section black, with a default text color of SpringGreen. If you don’t like SpringGreen, you can of course modify the script. Enjoy!
I’m only going to publish this one on bitbucket.org, since you have to use bitbucket before you’d need it.
