Make a new bug/new update

Minecraft is a great game, I love it. But in the other version the HOST of the game doesnt lag out, but the pocket edition does. When I walk in my worlds I lag out of the game, sometimes it shuts down my devices. There is also a lot of lag when I play on my favorite world. In addition, when I turn around or look around theres a glitch and it flicks the screen! Finally, what annoys me the most is when Im away from a place the paintings disappear and I have to wast more materials to put the poring back:(
List of suggestions: ??
•stained glass
•readable books
•chairs that we can sit on
•kitchen mods?!

Please do this!!! I would really appreciate it!!!!
Thank you!!!
