Looks pretty neat!
Can you move the files in the root folder so the package manager can install it with no issue? Right now the package manager (also if i clone the git repo) it creates this structure: User/SublimeTagmatcher/SublimeTagmatcher and it should be only User/SublimeTagmatcher.
Also, can you do the very same thing for brackets match? I mean instead of detecting tags to detect { } ( ) on js/php files (and other) ?
Thanks!
