Ever since I got my new MacBook Pro with Retina display, Text Wrangler, my text editor of choice has hurt my eyes as it has not been updated to take advantage of the my new high resolution display. There aren’t a lot of text editors to choose from in the world of freebies but luckily there is one that solves my problem.
Adobe also publishes a version of Brackets under the name Adobe Edge Code which has one extra feature that helps generate links to web fonts that Brackets does not. However, Brackets has a FAR superior icon, which for me, seals the deal. Mind you, both versions are still in beta.
