Hi,
After using Sublime Text 2 for few years, I finally took the leap of faith and migrated to Sublime Text 3. As some packages and configurations have changed, there are some things old-time users must learn. I wrote a blog post, based on my old ST2 tutorial, what ST3 can do and how you can pimp it up. This all is wrote from Python and web developer perspective. Also I shortly compare ST to other new kinds on the block (Brackets, Atom).
