Well, it's rare if I ever make a small suggestion,  but, here we go anyway.

I decided to put two suggestions in this thread since both are really short and are both kind of related (both being blocks you might have in your Tardis)

Block: Roundel Oven

Crafting: (Shapeless Recipe)

• Furnace
• Roundel 

GUI: It looks a bit like the furnace GUI, but it lacks a "Fuel" spot. Instead, there is a "cook" button.

Use: It cooks food.

Any other information:

• All Tardises generate with at least one somewhere if the player can find the roundel
• The Roundel oven ONLY cooks food. It will not smelt ores.
• It will also only work in the Tardis dimension or when powered by Redstone
• Has a small chance to overcook things
• Can become faulty. See this thread for more details

Block: Mirror

Crafting:

• Variant 1 (Recipe is WIP)
                                                                                         
  | Wooden Plank    | iron ingot | Glass Pane |
  | Wooden Fence   |  iron ingot | Glass Pane |
  | Woooden Plank |  iron ingot | Glass Pane |
• Variant 2
                                                                                                              
  |      Glass Pane      |     Glass Pane      |      Glass Pane      |
  |        iron ingot      |       iron ingot       |       iron ingot        |
  | Wooden Planks | Wooden Planks | Wooden Planks |

Use:

• The Mirror usually doesn't have anything loaded until the player is within 2 blocks in front of the said mirror
• The player will be able to see himself or herself.
• Great for Roleplay involving Regeneration.
• Great Block for decor

Variants:

• Stand-alone Mirror (2-3 blocks tall. 1 block wide and 1 block long)

• Wall Mirror/hanging mirror (or Bathroom Mirror to some)
  • 2-3 Blocks wide. 1-2 block tall. It is a nonsolid block

How do you suggest we implement this: Perhaps code from the U43 TB 6 Chunk Renderer, and latter builds where it functions similarly can be used

Block: Washing Machine Roundel

Crafting: (Shapeless Recipe)

• Roundel
• Cauldron 

GUI: 

• It has 4 slots, in which the player may put in either armor or banners.
• The player may also set a "Washing Level" which will determine how many layers will be removed from any banners in the washing machine Roundel

Uses: 

• It allows the player to remove multiple layers from a banner and wash multiple items at once.

Overwashing:

• Overwashing is a decrease in the Durability of an item left in a washer.
• I'm still deciding on the actual mechanics, but for now, I'm thinking it can happen when the washing machine roundel tries to wash something that has no dye layers to remove.

Other information:

• The washer does take time to wash things, but a Time-Space Device can be crafted and added to the Washer. This creates a time bubble around the machine, which speeds it up.
• The Washer will "Ding" at various intervals to let the player know that a washing level (the frame of time needed to remove one layer)  has been passed.
• The player may drag the items out of the washing machine at any time.

Block: Functioning hatstands (Perhaps with a few variants)

Originally Suggested by: 50ap5ud5 (Expanded on by Arcphoenix)

Crafting: 

| Stick |             Stick             | Stick |

|    Air  |    Wooden Fence     |   Air   |

|    Air    |        Wooden plank         |    Air    |  

Uses: 

Up to 4 hats/helmets can be added to a hatstand at one time.

How do you Suggest we implement this:  Perhaps the hatstand could use attributes similar to armour stands

Variants:

• Fourth Doctor's Hatstand
• Fifth Doctor's Hatstand (the one from Frontios)
• I may add a few more later

Other information: Not atm

Update:

Added Washing Machine Roundel

Added 50ap5ud5's idea for functioning hatstands.

Also, changed a bit of the mirror suggestion, since the Chunk Renderer block is now a bit different

Crafting roundel, more storage roundels. my umbrella, both a block and an item (Maybe), and the toy tardis seen in "Let's Kill Hitler". Enjoy your list. Free of charge. 

maybe add some more eteriors like maybe a trophy case (fridge could be used as a base)or maybe a funace roundel

 Sure, I'll add these later 

 Eteriors? DO you mean Exteriors?

yeah 

Well, this thread is only for minor miscellaneous utility blocks

I recommend seeing one of these threads though if you have any ideas for Tardis Exteriors

I'm sitting here thinking about the washing roundel and I actually dislike your approach to it. I personally would rather see mechanics similar to the washing machine in Mr.Crayfish's Furniture Mod where it actually repairs armor by "washing" it. It'd require soap or "Tardis energy" whatever that might be. (Arctron, Ziton-7, or other stuff) But that might just me.
