They are part of the Qlik Sense product and not from In4BI's Platform Manager.
QMC --> left side panel --> sync rules at bottom.
Edit the rules for each node as necessary. Central dont have to dont anything, but other RIM nodes, you have to modify them to sync only apps that you need. Usually i have written a rule to sync only my work stream on DEV-RIM.
here is one sample rules not to copy monitoring stream and apps inside them.
((resource.stream.name!="Monitoring apps" or resource.name!="License Monitor" or resource.name!="Operations Monitor"))
As you and Martin know, I'm a big fan of Platform Manager. One feature that you didn't mention is Global Search. I use that all the time to find where our sensitive data lives.. We will look into using Platform Manager for Qlik Sense as well in the future when we have our long term Qlik licensing and architecture finalized. The process flow I attached is for those who don't have an idea of where to start when you don't have Platform Manager and you're developing in a production site.
