Where can I find the folder to add custom themes for ST within Lion? Thanks.
Lion has hidden the ~/Library folder in Finder, so it's a bit tricky to get to. The simplest option is to use the "Preferences/Browse Packages" menu.
Awesome! Got it! thanks
Or if you want to get to it from Finder, you can press "Go > Go to Folder" (Shift + Command + G) and type "~/Library/Application Support/Sublime Text 2/Packages/" (btw, this supports tab completion for each folder...)
