More Glass Blocks, please. (Stairs, Doors, Trapdoors and other furnishings)

It feels as if we still don't have enough craftable glass blocks. The stained glass are simply recolors, I feel as if there could perhaps be more. With glass doors and trapdoors, we could potentially be able to make clear glass tubings for some contraptions such as the bubble columns. If do this to ordinary glass blocks right now, it doesn't look much appealing.

Edit: Also, there could be some sort of glass case where we can display items similar to item-frames, but is preserved inside glass. We wouldn't need to clip armor stands in glass blocks anymore, instead we get a more stylish case.
