Bare Bones has updated their super awesome text editor, BBEdit, all the way to 11. I use BBEdit every day for all kinds of text editing tasks, and I've been using it for almost 20 years now (I believe I first started using it to edit HTML files with version 3.5).
It's an amazing and deep app, one of my favorites of all time. And I suspect it'll keep on keeping on, staying relevant, until the heat death of the universe.
It doesn't suck.
