Enhanced logging activity

There's already an idea about setting the log level. Here I'd like to propose another enhancement to the Log activity.

We try to use a prefix with every Log activity, in order to easily identify where (from which workflow) a message is coming from. A typical Log message would be

=$logPrefix.value + " this is a message"

But when we need to log an entire object (e.g. a featureSet) this is not possible, because the console would just show "[MyWorkflow] - [object Object]", whereas if we just log the object, it is possible to expand the object's properties in the console.

It would be nice if the Log activity had a second optional input of type Object that would display the entire object, or maybe a JSON represention in addition to the (existing) message
