The language are the only thing that you can't use at 100%, because I don't think anybody knows how to code in all of them. But if you add up every needs for the community, it's a need. if you don't get syntax highlighting, I don't think it's worth using that editor (even if it's Sublime Text ).
Me either didn't use the other features, simply because I wasn't aware of them. Once you are, you find a way to use them everywhere, and it saves you a lot of time. Now, I can't use any editor that doesn't have them.
If you could open whatever file in your browser, with a default stylesheet (customisable if you like CSS), would it suits your needs?
It's really easy to do, less than 5 mins. I really think it's something you're going to regret, not using Sublime Text because of a print feature.
