Every so often I try a dark theme in Xcode, and usually switch back to the default within a few days. But since I’ve been using the EGOv2, it actually seems to be sticking. There’s also an original version of EGO that v2 is based off of that’s alright as well, although a little too high contrast for me. The themes use 13pt Menlo Bold as their font — which is a different than what I’m used to. I’m actually liking the 13pt size, but turned off bold.
