When you are looking in the trapped chest it send a redstone signal. And when hopper gets a redstone signal it stops placing. But it should be like the piston like you cant power it from the front of it.
For feature suggestions/changes please use the MineCraft Forums: Suggestions.
By looking into a trapped chest you activate it. This disables the Hopper.
