Hey Roman,
Thanks for reaching out!
Regardless of whether you have a license or not, pulling off the customizations you describe isn’t possible at this time just by adding a specific plugin to your site — the customizations describe are possible, but would unfortunately require code customizations to implement 🙁
You would have to write that custom code or hire a professional developer to do it for you. We have a list of great developers here → http://m.tri.be/18k1 (and have no affiliation with any of these folks—they’re simply some well-respected names in the community that we’ve compiled to share in situations like this one).
Sorry to bear this news! Please let me know if there are any other issues or questions I can try to help with.
Sincerely,
George
