Great Plugin for Osclass payment solution.
Moreover, I think these below-defined function can make this plugin more awesome.
1. Setting up the plugin in a manner that user can buy Premium and Highlight together with discounted price.
2. The plugin still needs to be more attractive(especially Mobile view), after all, we are gonna charge customer here.
3. In the section of Affiliate, we can use font awesome icons for sharing buttons in order to make more attractive this page in mobile view also.
4. In the section of Membership, when I select first to be a platinum group member it worked very well but after that when I buy a membership in silver group it was also done I mean it should prevent me to do that or it should return with like (i.e. your membership is extended now you are Platinium member till XX:XX:xxxx and after that silver member till xx:xx:xxxx.)
As per I think.
5. The last one is if the user can promote their listing from users tools instead of using the hook below the item, it can be more attractive especially for Veronika and Zara theme. Maybe of the plugins like related listing plugin and other. it may ruin the User experience to fulfill that Payment session.
However, Suggestion doesn't mean to be done it could be expensive in terms of any other things that I don't know.
Great work was done by MB themes, have a great sell ahead!
