I have used another extension that doing the same thing, it's a commercial extension but it's working fine so it's worth the money.
EFSEO works with every Yootheme template that I have tested. I have a membership from Yootheme and have tested it several times.
You have not contacted me via email or the support forum, because you have not really tested EFSEO. If you had, you would see that EFSEO also works in Yootheme templates. And if you really got a problem, then you would have contacted me and would not buy immediately a commercial extensions which do nothing more as my free extension.
I had a problem controlling the Meta tags and title of certain pages of my site, with the help of this plugin I can control all types of pages and component.
One of the problems I had is controling of Meta tags in my CCBORD forum, using this component I changed the tags and the titles in my forum's posts.
