This is a small thing but i personally think that this would be awesome!
You probably know that in the new 1.8 Minecraft update you can customize the block models of minecraft in resource packs.
What if we could enable and disable 3D blocks in Mine-Imator?!?!
This feature would make my thumbnails and background for my friends alot better as i often use vines, ladders etc. And it would look much better with 3D ladders and vines!
I know this is a small thing but i think it would make a huge diffirence.
