Thanks for your feedback.
This is the reason for my post.
I'm suggesting the indication on the OsclassPoint marketplace, in the product technical specification, in the Osclass Support line, if a plugin doesn't make sense for a specific version, it should not be supported by that version, or, an indication of "included in version xx".
This would avoid some time consuming and disappointment process while trying install a plug-in just to verify it isn't really necessary.
Osclass looks like promising, i'll keep looking for a setup that allows me to start my business, making money, and then investing it in developing and adding more features from OsclassPoint.
But it has to have this order :-), or otherwise won't work, setup business with Osclass using base features, and some featurefull, but less expensive plug-ins, make some money, invest that money on Osclass and OsclassPoint :-)
Thank for your feedback.
