Hi,
I did a search here and can’t find what I’m looking for exactly. Currently, the auto complete drop down menu displays both actual tab completions from plugins, and words that are used on the page. Is it possible to only disable the latter?

Yes, the plugin will have to return its completions as: return (my_completions, sublime.INHIBIT_WORD_COMPLETIONS | sublime.INHIBIT_EXPLICIT_COMPLETIONS)
