I like your topic that is why I want to talk about some upcoming update too.
- There is no just english lang. also there many languages who use accent letter in url , cat , tags.In sitemap they look very badly. So there has to be ability to change url slug and also description for cat and tags.
- Plugins dont work with all versions.For example I want to use 1.8* but Some plugins dont work with it.Like ultimate seo , Advansed Tag Desciption.
- Also Developer have to take care about "Seo" in q2a.At least there has to be seo tools like Ultimate seo.
I want to see theme in future upcoming update.If could be it will be more good.
