So.. I think BBEdit is very extensible. The trouble is that there isn't a community building and publishing good extensions. One thing I do like is features like "codeless syntax modules". I've built syntax coloring for various obscure languages in about 15 minutes using this feature. (of course had I been using emacs I would have been able to get the feature in a few minutes with a web search and download).
