Projects in Sublime Text 2

You can add the first folder by opening it(cmd+o) or add it by dragging it into the SublimeText view.

Also if you wish to remove project from the quick switch list you can do so by editing the recent_workspaces array in the Session.sublime_session. On osX you can find it under /Users/USER_NAME/Library/Application Support/Sublime Text 2/Settings/
