So let's see what ideas become true as of now (2016/4/30):

\......

7. Cannons (dispensers, actually) with different functions: There are Key dispensers now.

16. Oven (Evil Spawners)

32. Track Tile (becomes conveyor belts)

34. Blocker Machine (Evil Spawners)

And then I have some new ones:

Picky Teleporters: A certain color of candy cannot drop down through the teleporters, and on top of that, block any candies that wants to come down. This can also specifically block bombs of licorice swirls, depending on the setup.
