Add New Creative Mode Tabs

Hello! With the latest updates Minecraft has been getting it has become more and more apparent that, the game has a lot of new blocks, and items in general. The current tabs we have in creative mode are not enough to properly organize everything, and the "Building Blocks" tab is being flooded with basically every new update. I would suggest the creation of at least two or three new tabs (if anyone has other ideas for additional tabs, please make your thoughts known).

- A tab meant for the storage of all "non-block blocks", basically all the slabs, stairs, walls, and fences in the game. The only problem with this idea is I can't think of what you'd call it. 

- Separate a pre-existing tab, the "Decoration" one I think it is called, with the creation of a "Nature" tab for all things nature themed or related. Decoration can still be kept with all the blocks typically used or meant for well, decoration. 

- The creation of a stone specific tab, this one isn't that necessary I will admit, but the game has a lot of blocks that fit under this categorization so I believe it might be needed.
