Please add an entry on this page showing your name / username / handle or whatever and describing how you use TagHighlight (any options that you set, anything quirky that you do, what language source files you use it with etc). I'll start:
TagHLConfig.txt used for configuration, contents:
ReloadColourScheme:True SetWorkingDir:True EnableCscope:True ExtensionLanguageOverrides: hg:all diff:all
Being the lead developer of TagHighlight, I don't really need to tweak very much as I wrote the defaults around the way I wanted to use it. I use ReloadColourScheme because on one of my machines I've found the colours aren't being maintained properly. I suspect this is something to do with a bug in one version of Vim with "hi default", but I'm not sure. I use the ExtensionLanguageOverrides to highlight types in Mercurial commit messages.
