I like Appcode's formatting tools, and could configure it how I like. (I'm only picky about one or two things stylistically, and one or two things that affect code generation: what Appcode does when it generates an @property for me, for example).
I haven't tried sharing these styles across the team who uses AppCode. I'd really like to be able to share styles across IDEs: if some of the team uses XCode they could use the style I've defined. But I don't see a way to share these cross-tool either.
Even Uncrustify integration (export?) for Appcode would be nice, but it's missing. Heck, I'd even like Uncrustify in AppCode, but haven't found a plugin for it.
