Thought it may be helpful to have the preview have an option to be in "layers", Have an option to show the whole preview, then another option to first show the inner sphere (the Redstone bits up to tier 7) and once that is complete, have the draconic blocks show. Might be a tad easier to see when building.

Just a thought :)

Yes it would!
(Though you may want to consider pointing out It's for the orb in the title!)

That is gonna be a lifesaver. You my friend is a genius.

Not my most elegant solution but this will be in the next update.
