Yes, please. I am very interested in this. I feel as though I've only scratched the surface of what ST2 can do even though I've been using it for the last year and experimented with writing my own plugins.
I'd also love to see a "cheat-sheet" for shortcut keys.
To be honest, my ebook is on initial stage, but I'm actively working on it. If you want to track its progress, here's its repository on GitHub: https://github.com/elomarns/sublime-coding
Anyway you can find a great cheat sheet on the links below:
