Unfortunately the minimalistic approach of xF itself and the authors of it, doesn't lend to them doing too much when it comes to making options for the masses. It seems that they'd rather stick to the Apple way of doing things and saying "Here, drink this kool-aid, you like it.". Not that xF is a bad product, what they have done is really nice and I like it a lot. But they don't seem to encourage modding the software, at least from a marketing perspective on their site. Maybe it's just early in their roadmap and we'll see more later, hopefully so.
To be fair though, I think more than anything, it's the community there that annoys the hell out of me. So many people with their heads so far up their own asses... you can't ask a simple question because it's beneath them to answer. When you do ask a question, they continually question you as to "WHY?!" you need/want such a thing, even though they themselves aren't even going to code it. Everyone wants to tell everyone what and how to do things there instead of just shutting the hell up if it's not something they are personally interested in. Sadly, the vB forums are much nicer when to comes to how the mod community treats each other. I think it's because many on the xF mod community consider themselves above anyone else and are basically elitist jerks.
Anyway, sorry for the rant, I like xF, plan on using xF and hope it succeeds in all ways. I just dislike what I've seen of the majority of the community there and how the mods let the elitists treat other paying customers of xF.
