Name of feature: Tardis Custom Interior Blueprint System:

Description: Let's imagine for a while that you just finished a custom interior and you love it very much, ok. You take a blueprint from your chest, get out of your Tardis, shift+right click with the blueprint on your hand, and the interior of it, is in the blueprint, you're going to do other world, or you want the same Tardis on multiplayer, and you take a Template Tardis, and do shift+left click with the before used blueprint, and the Template Tardis has the interior you had made, BUT if you don't have the materials (it tells how many blocks you need) it doesn't work.

How it affects to the gameplay: If your friend liked your Tardis but you don't want him to be able to build/control it, you pass him a blueprint, or he can use one. But the name of the original builder would stay on the blueprint.

I've always felt that this should be a feature, especially requiring the player to have the necessary blocks, so this has my full support. We'd need to make server rules about them though, so that they don't overlap the Tardises of other players (namely those in the Tardis line) when spawned.

 Thanks man! :D
