unless there's an easy way not to install certain blocks okay, otherwise I'd like to keep it simple and small...

I know there's the advanced permission mode but I don't like to add this kind of complexicity if not necessary.

Also, the block isn't free. Why should he put it in the core for free? People have to make money. Would you pay him to include it in the core??

Also, it seems to be easier to install blocks from the marketplace in the upcoming 5.4 version...
