Premium Theme benefits

Hi

After several weeks testing I would want to purchase premium version of your awesome theme but firstly it’d be better if I could know more about several questions:

– Can I set a related posts plugin in the footer?
I would like to show related posts conditioned to the category of the post.

– I think I could read somewhere on internet that premium version let me show post pics 100% responsive, right?
Now it’s impossible (maybe I’m doing something wrong. I’m a newbie)

– I’d like to get more layouts for posts (better than building every post with the builder).

– Could it be possible to place logo on the ribbon header?

Thank you so much
