I'm presently trying to build an Omnibox extension, but I'll be damned if I can figure out how.
So far, the closest I've got is an Omnibox example for internal usage, within an organisation. But I'm not sure how to re-work this for my own purposes; feeding in suggestions from an external data source.
I've scoured Google and found nothing of any note or practical use (that I can find).
Does anyone know of any good resources / example that might help?
