I would like to see a default mobile style provided with XenForo software, out of the box. IMHO, this should have already happened, we are way behind the gear on this one. ~peace
Honestly I don't see a need for Xenforo to develop an app when you have 3rd party ones filling the niche, I'd rather see the time built on developing other new things for the core. That said even with no mobile style Xenforo is one of the easier sites to navigate around that I've seen.
I fully support that concept. sincerely. an efficient mobile style goes a long way, and like I said can be made to switch to mobile style automatically when mobile devices sign on .. you dont really need the app if the mobile style is efficient and robust
