Minecraft Concepts

[Ngugu]

What do you think would be fitting to have in Minecraft as an update? Personally, I'd like to see:
1. Being able to break glass, glowstone, redstone, etc. by shooting an arrow at it
2. Water-filled cauldrons hydrating tilled soil
3. Growing specific crops in flower pots
4. Climbable rope
5. Additional doors, trapdoors, half-doors of different materials (Glass, Iron, Other Wood types)
6. Tables, chairs and shelves
7. Lighting fixes
8. Metal ladders
9. Linkable cocopans
10. Sittable chairs and stair blocks
11. More light fixtures
12. Redstone-infused walls
13. Additional paintings and option to choose which one to place
14. Openable windows
15. Cloud fix
16. Y-axis build limit increased to 512 (Anyone who's building skyscrapers will rejoice)
17. Block damage

I'm sure there are mods for all of these, but to actually have them implemented into Vanilla Minecraft would be lovely. Feel free to post your ideas and opinions.
