Somewhere in my Minecraft PE world, I wanted to build another such structure that is not yet implemented in MCPE. One small building has a bunch of books in it with some open space in the center. Can you guess what I was trying to build? Right! A room for Enchanting! I actually wanted to make an underground floor or some kind of hidden area where you could do some enchanting if you were fortunate enough to find it. Also, I wanted to make a hidden space so you could try to get the best possible enchantment. You all may be familiar with this feeling if you've played certain RPGs or something- you find some sort of hidden zone that features an awesome area for where you could get some crazy powerups or some very powerful items. That's what I was trying to create.
Just because MCPE doesn't have certain features implemented doesn't mean you still can't have fun making certain structures for them. I am even thinking of making a horse stable for if MCPE gets horses. Speaking of animals, I am pretty impressed with the various passive animal mobs in Minecraft. I saw two videos on the ocelot. One was a cute and funny video while another was simply a look at the Snapshot that included ocelots. I love cats and horses, so I was most certainly pleased to see these animals among the passive mobs. I would probably hate to try to breed an ocelot if I were playing Minecraft, though. It would be a fussbudget to try to tame an ocelot without scaring the daylights out of one. What is cute is that mating ocelots will come along with kittens. Ocelots and kittens even follow you around once tamed. Always cute. I think I even found out Creepers don't like ocelots or that they don't attack Creepers. Something like that...
Besides that, I learned about using those trapdoors. Some of the businesses (such as inns) in my Minecraft world have counters, but blocked off with fence gates rather than trapdoors. I'll replace some of those fence gates at businesses with trapdoors.
