This enhancement is strongly needed. Now my Q&A is indexed and I have tons of duplicate TITLE tags errors. Descriptions needed too, but this is not that big problem in my opionion, because google can get descrption from content, and it is not shown as error. But duplicate TITLE's, this is error. Any idea? I know, how to edit core pages, but this is bad idea because q&a updates. Anybody working on plugin?
