Mobile Stacker

Would be great if the stacker was not fixed and had a degree of mobility to cover a target area. This functionality could be incorporated in the absent version 2 of the Stacker.
Ideally you could set a target area. (Similar to dumping zone) The stacker arm/boom would utilise a limited amount of swing angle and telescoping to cover that target zone; whilst also respecting its dump offset restriction (great feature btw).
I'm quite a fan of dumping materials to build land bridges, especially with so many of the new custom maps being archipelagos. With no ferry/ workboats, or flight option: Trying to get to that island with a rich resource deposit? Right now its a combination of setting dumping zones and building/removing/rebuilding stackers. This is tedious, but faster than dumping alone. So unfortunately its necessary right now.

It would be nice if you can rotate the the tip in an 180 degree range and extend / shorten the stacker with one click (construction triggered)

Yes please, a Radial Stacker with Telescoping would be an excellent Tier 2 addition to the game. Provides the flexibility of not having to build multiple generic Stackers to cover an area.

Very good idea. If it's not possible to implement, please at least consider some buildings to "move" (or dismantle and rebuild - maybe with higher speed than regular construction) without penalty (in case 100% refund is not activated). I think stackers and also maybe conveyors/rails/pipes etc. should be movable without loosing ressources. Especially for the stacker it does not seem right to loose material to move it one chunk to the side.
