ID List Room *poll*

[challenger410]

Since the Flat World is only accessible to build on, by people who can spawn blocks, I thought that it would logical to have an Spawn Item ID room, instead of a shop. The question I have for you guys is the idea of convenience. Would it be nicer too separate blocks into groups by there ID number, or should i seperate them by item groups?

E.G.
items 1-50 in this room
51-100 in the next
etc.

OR

E.G.
Building Blocks in this room
Redstone items in this room
Etc.
