Hi there,
Is there (will) a feature to auto generate meta information from title/desciption for ES/ED/EB and content ?
Actually, title/description or metadata for post/website is already there. You can view them by "viewing page source" as shown
http://prntscr.com/cy8da4. The purpose of Metaman is to change current metadata for your site/post.
For example, there are no images included in a blog post for EasyBlog's post. Image metadata is set to icon/logo/log-in of your site. But, you want to show different images rather than icon/logo/log-in of your site image. You can use Metaman to show other image rather by uploading it rather than using your logo/icon/log-in image.
Hope this help.
