In case you missed it the Dev team posted new info yesterday and this was included:
So I wanted to break it down a bit:
1. Copy/Paste Tool - This would be interesting in a live environment but there would need to be some sort of limitation if you want to incorporate it without a build mode.
2. Undo - Yes please, if not undo then a way to easily remove recently placed blocks without a resource deficit
3. Smoother - With Voxels this will be a must otherwise there will be some janky ships out there as well as frustration.
4. Voxel Elements - This would be the limitation of the copy paste, would need to see it in action depending on the types of things you can make.
5. Visual Aids - As I stated in another post it would be great to have an overlay of information that you can access as a "New View" type of thing. With Voxels not sure how a grid will look, but with frames and even holograms this would be cool. Also I really want a block count for your structures, both for the overall and as you place rows of blocks would be awesome!
