2D mapping grid

I would like to see a 2-dimensional mapping grid.
This could allow the user to very quickly create a layout of a dungeon, castle, tavern, or anything.
Add on the option to tag them as what they are going to be.
Tavern, hallway, latrine, stairway up, stairway down, etc

Then they can drop the 2D grid onto a terrain of their choice and dress it up.
Or use the designated Tags to allow Dungeon Alchemist to dress it
