Add new paid features. Now only premium, raise the ad and highlight the ad. For example, add the label Stock, Urgent Sale, and so on. It would not be bad to give the buyers of this plugin the opportunity to add paid services themselves. And there are very few existing ones, as practice shows. Users need great features that they are willing to pay for.

Unfortunatelly that is technically too complex and not worth of such time investment.
New premium options may be considered in future.

Please consider adding it. This is necessary not only for visitors, but also for buyers of this plugin. Thanks

Is it possible to create additional features based on the existing premium features yourself? Is it really difficult? If so, try to make them yourself. You will definitely increase the sales of this plugin and give the buyers of this plugin the opportunity to increase sales. It is then that this plugin will become full-fledged and has no analogues in Osclass. Thank you in advance)
