Things Minecraft should add

I've got some ideas that Minecraft should add. -Glass Doors: it would be cool if you could use glass panes to craft them with and it would bring more creativity and detail to the game. -Connectable Rail Roads: It would be very useful to be able to connect two (or more) separate rail roads. - Sweet Berry/Glow Berry Juice: Another option besides water and honey. -More Crystals (like ruby, rose quartz, etc): Just thought it would be cool. -Deciduous Biome: A mixed biome of spruce, oak, bitch, and polar would be beautiful. -Dog Texture: I feel like the wolf should change to a dog when you tame it, like cats. It would just make sense. - Dyeable Blocks: It would be amazing if you could dye wood or bricks. I suck at typing and writing and I'm sorry for that. But please take these ideas into consideration.
