Try to get Multicraft as new application
Multicraft is a pice of software that will allow you to create Mincraft servers via your own website from the app. This will make plesk more interesting to people that want to create Minecraft servers. Multicraft is a pice of software that costs money, so maybe that if you talk to them you can add it under the category Gaming or something.
Sorry, we don’t plan for Multicraft. As APS package format is open and documented, you can pack it yourself.
