A couple of improvements to the deconstruction function that I thought of while tearing down a rather large building.
Instant Deconstruct - Have a key you can hold down while deconstructing to remove the need to press and hold.
Deconstruct and trash - another key you can hold that would automatically trash what you deconstruct rather than refund the parts so you don't end up with boxes everywhere (exceptions being any limited resources, hub parts, slugs/power shards, spheres and loops, hard drives)
Perhaps not a press and hold for both as it would be a pain to hold down both keys. Perhaps hold Ctrl for instant deconstruct, then alt to toggle resource refunds which then brings up an obvious overlay to the UI to warn that parts won't be refunded.
