Hey there really great mod. Love it :).

• As a suggestion for the builder with the space chamber card: I would be nice if grassblocks would be repalceable with dirt. Its really hard to get all that grassblocks (esp. with the quarry-card-bug).
• Similar thing for trees (esp. leaves). An option to simply spare them would be great.
• Additionally it might be good to add an option to set a solid layer at the bottom of a copied area so that sand thats gona be copied doesnt fall down and therefor doesnt need to replaced multiply times.

greetings Rigor

Note that the third suggestion is already supported. Just enable the support blocks and they will prevent sand/water from falling down during the move/copy process
