Chocolat Text Editor
If you’re feeling bored with Textwrangler and want to try a new text editor, take a look at Chocolat. It’s got the usual features plus another few: Dreamweaver-like code hinting, tabs, and a project drawer that just shows the files available in the current directory.
It’s free for now only because it’s still being developed (and might crash on you), so you’ll eventually have to pay for it. Still, worth a look.
