Sublime Text plugin to make ST users work together with CSS Edit users.
Use package control, or create a new folder inside your /packages folder, and copy the file into that folder.
add
{ "keys": ["command+l"], "command": "css_groups" }
..to your user keymap and you will be good to go.
Whenever you are inside a CSS file that contains CSS edit's Group information (like /* @group Headings */ )
press command+l and you will be presented with a navigation list to jump around with in the CSS file.
Update: Also works for Sublime Text 3 now.
