After multiple "we will never implement this" teleporter allowed to move items and crop's trampling fixed.
Soo now i suggest to allow moving teleporter face with wrench and expect "wont implement this never" answer and such feature 2-4 versions later.
If implemented properly this will allow building interesting systems that manipulate entity velocity and hardtodetect without xray traps.
This will also need vector utils to operate velocity and addition of projectiles into allowed list (arrows and littnt)
Also disable particles if nontransperent block placed infront of teleporter face and move exitpoint one block futher. This will allow "hightech" dispenser cannons, invisible and undetectable. With tnt more advancet tnt cannons will be possible.
