I think it would be cool to have a block in the game that you can use to toggle a scanner like system where if a block is not affected or protected by a bubble it would light change its color to like blue or something. to expand on this idea you can have upgrades for it similar to the component factory upgrades, maybe one for shields and one for repair bubbles. maybe the shield will be blue and repair to be green. but the downside would probably be that the player will just stick it to the top and store it into the SCU once their done with it, basically they wouldn't really incorporate it into the tech, i know i would. it would be nice though.
