New Features for the Decorated Pot

The new decorated pots are awesome, but there was one disappointment the first time I saw them in the game. If only we were able to put two-block-tall plants (rose bushes, lilac, sunflower etc.) in these pots! It would add a lot of characteristics and designing abilities to the game. 

For solving the problem as they also function as a storage, I suggest having to add water (via a water bucket or water bottle) to the pot which then will be able to hold those plants! Maybe breaking the pot would cause the water to flow?

There could also be another feature, making custom flower pots! By adding four different one-block-tall plants in the different positions of the pot, you can make a special pot of flowers for yourself.

Also, maybe being able to engrave the patterns on them? With a chisel tool maybe?
