So I think you know my answer already, and while it is slow to set up, it is 100% personal, and therefore I find it quicker in the long run. I don’t have to learn other people’s snippets, as I make them to suit me!
I use CodeBox, which I think is a really great program. Re workflow: you can access all of your snippets via the menu bar with a key command and easily insert them into your ST 2 page, even if CB is not running.
Heck, you can even theme it using your TM or ST theme.
