I downloaded BracketHighlighter-BH2ST3.zip from github and can't get it to work with ST3. If I put the files in SublimeText\Data\Packages\BracketHighlighter, then I get error in console:
If I put the files in SublimeText\Data\Packages\User\BracketHighlighter, then I get no errors in the console. But then if I go to Preferences > Package Settings > Bracket Settings - Default, I get an empty file because it loads SublimeText\Data\Packages\BracketHighlighter\bh_core.sublime-settings.
So either way it is not fully working. Perhaps this is relevant: Data\Packages\User is a cryptic nested dir structure.
