A few more Sublime Text plugins worth checking out:

AdvancedNewFile -- easy file/directory creation

Alignment -- shortcut for instant alignment

Emmet -- essential for HTML/CSS

GitGutter -- see diff marks in gutter

Origami -- additional shortcuts for split panes

VintageEx -- emulation of Vim's Ex-mode

The Vim emulation isn't one-to-one, but it's pretty good with Vintage mode enabled and the VintageEx plugin installed.
