WTH isn't generic thermostat a helper?

The generic thermostat where you can use any temperatur input to control any heater or relay output is super helpful! But it’s only configurable via YAML. WTH is this not possible to set up from the UI?

A very large number of parameters to do via a ui. Don’t fear the yaml.

This is now implemented. For advanced functions you still have to use YAML but basic setup works as a helper.
