Dropper Post Color

Love the update!

In regards to the dropper post color, right now when you change the color of the actual sliding portion of the dropper it changes the color of the whole dropper, is it possible to have two different colors, one for the post and one for the sliding portion, similar to the Fox Transfer?

Also it would be really awesome to have an overlay of tubes w/ butting profiles on the tubes to ensure everything fits. Right now I am stuck bringing everything into autocad and that is a real PITA.
