Inventory problem solution, block variants.

Make so that every block variant drops its original block.

For example: spruce doors, gates, trapdoors, all of those drops just spruce planks.

What it for? 
It basically gives you 9+ more slots for other blocks. Great for survival

• Issue1: what about slabs? Are double slabs drops two?
• Solution: second slab can be placed for free, its a slab after all, why would it take 2 full blocks for 1 block
• Issue2: it would be very tideous to select block variants through a wheel/hammer/idk every time. Solution: filter slots, choose what you want to be into that slot, f.e. slab or door. And creative menu can still have block variants, while in survival it not a problem at all (usually).
• Issue3: bedrock players. 
• Solution for mobile: another button on screen huh? And hold on slot to set a filter. For consoles: As I know, controller have Craft and Inventory buttons, so maybe replace Craft with block variant wheel? It could have other stuff, not just variants. Or Solution2: Hammer item (meh)

By the way, we need more inventory space :3 add fourth row
