EA Powertools ( https://github.com/eapowertools ) is a set of -incredibly- tools developed by a small team and distributed freely.
It can answer to many use case.
However :
1/ it's not supported by Qlik
2/some installations are painful (e.g. for the telemetry dashboard, you cannot edit the reload task due to a qlik limitation)
I think these tools should be built-in and supported by Qlik.
