The RM Rule is capable to set and/or reset Private Boolean for ANY RM rule.
It will be very helpful if RM Rule also can check a Status of ANY RM Rule Private Boolean.
The use case is - a better synchronization of multiple dependent RM rules.
As of now it is possible to create a Hub Variable but the problem is - Hub Variables
responsiveness is not fast enough. From the other side the responsiveness of
Private Boolean built-in variables is much faster.
Since any given RM rule can manipulate a PB of any other RM rule (so, PB already is not a
100% PB) I don't see why any given RM rule cannot check a status of any other RM rule.
Another possibility is to create a "RM Rule Status Indicator" (active/idle).
