Someone never played 0002 or RtB...
Movers are 100% possible.
We just need the code support and tools :v
This is why I say talk of whether something is possible should be left to the people who know what they're talking about.
In 0002, bricks used the default StaticShape class and could be freely manipulated, moved, rotated, etc.
In the current version, bricks use a specifically coded fxDTSBrick class. Bricks are locked to a grid. They can not be moved out of this grid before placement, and can not be moved at all after placement.
Add-ons like JVS that feature moving "bricks" are just an invisible brick with a static shape mounted to it.
