Hey, I never said we shouldn't have a complete feature set. I agree with 
you. IMO it should not have even been committed without the ability to 
actually know what is going on and we have had it since (in theory) 8.1?

My primary concern is: Don't make it stupid.

I liked Claudio's comment, "More than easy, it should be obvious.".

It should be obvious from a review of the documentation how to manage 
this stuff. It isn't, and worse even if we wrote the documentation it 
still isn't because the feature is not complete.

With great power comes great responsibility.... :P
