There have been multiple times that I have build my custom TARDIS interior and I'm just about ready to add the time rotor. I add the rotor but then... its either too tall or two short for what I need.

My suggestion is to brake up nearly all the blocks that are multiple blocks in size so that the player can make said block as big or small as they need. like, if someone prefers the Toyota rotors, but their TARDIS is much taller than the rotor, they can make a 4, 10, even a 50 block tall rotor. This could be applied to more than just the rotors too

For example, the 8th Doctors and copper monitor could be broken up into at least three block. The Monitor, The hanging mechanism, and the top.

Blocks like the Hartnell console panels and the back wall could be broken up to. The panels could take up into one block instead of three. The back wall, admittedly, might be a bit difficult to split up, but it would give so many more options when people are building their TARDIS's

Im not sure how difficult this would be to add to the mod, So Im not expecting it any time soon.

you'll see below, two Photoshop edits of my idea. with the blue Toyota and copper rotors as my subject

I really like this suggestion! I have also had the same problem. However, it just might mean the inventory might become crowded, so there might have to be a separate 'Time Rotor' tab. But, other than that, it is only crafting recipes. I believe the SWD team has been focusing on making many blocks craftable recently, and so this is where you would come across a problem. However, if there was any way around this then I definitely think that it should be added!
