Nicer Pictures with new Building Block

When a new Building Block is added that doesn't have a channel input, Harmony always displays a channel that is selected by some unknown algorithm. Unfortunately, if that channel is rubbish / not relevant, each new building block is added with the same useless image displayed first.

A better choice would be the last channel select a used made.

You have some populations detected and add a Calculate Property, or a Select Population building block. Harmony shows first the regions of the population on the "Default" = BAD image. If it would use the channels from the last building block that was added, it would look much more consistent.
