Thanks for the references. It's always useful to have more information.
I've used this when I wrote some plugins and tweaked sublime and honestly I have to say I found it lacking in detail and incomplete.
This is still incomplete (and costs $20). Once it's complete remains to be seen how useful it would be.
This is more of a general introduction if you've never used sublime before, but but gives only the most general information.
For sublime to succeed it needs complete documentation.
If you poke around sublime you already see settings, files, structures, API calls, system variables and other such constructs that the programmer has already developed and they work. You can use them and they work if you know the right way. But most of it is not documented.
This can even be built as a wiki and will be fast and easy to do with the help of sublime users, but the developer has the most knowledge so he needs to be willing to share and start the ball rolling
Post here if you know of more Sublime reference sources.
