Thank you so much for your question and good suggestion regarding our theme. We really appreciate your suggestion and try to implement it on theme too.
Based on your problem, you can choose any of the sidebar on each post and page. You can set sidebar individually on each page and post. But, what you mean to say, ” we have content we want displayed while on the front page and do not need all of it displayed while users are in our posts”? Please elaborate this section and please post your site URL so that we can find the exact issue and find the best solutions for it.
