Hi, I'm new to the forum (but I've already a couple of dozen hours of play on Besiege) and was checking the other suggestions before writing down mine. This one in particular would be a really helpful implementation but it needs another one that still miss (and it's really useful too): the possibility to move around certain parts of the project and not only it as a whole. For example I build something then i discover that a whole part needs to be 2-3 blocks higher than the rest, as it is now my only option is to delete and build again one of the two parts entirely since i cannot adjust the height of just some of the blocks. Talking about "importing" smaller projects/pieces it would be an indispensable feature, and it would be really cool even alone!
