I would gladly pay for a pro version of this theme if it came with the ability to ask specific questions of a support person and get a response, even if it’s by email.
Support through a user forum is (sometimes) better than nothing, but I need to ask a couple of questions and know that I will get an answer from someone who knows the theme, and in a reasonable period of time.
I would gladly offer this service if I had the means. Currently I’m the only person running this website and my availability is limited. You are free to search the forum and post your own question. That’s why it’s a forum, so you still have a chance to find your answer when I’m not around.
