Suggestion Features for the next Update.

Do you guys think you can add some new features in your new update? 

1. A pressure plate block type option for blocks like the slab type.

2. A door block type for the blocks. (This might be hard)

3. Add an option for Living Entities (mobs) to make the mob only spawn on a specific block. (or blocks)

Edit: 2021: Heh, all of these are pretty much added almost a year later
