In 1.1 the selection drag tool was based on the entity collision box which made it very convenient and useful for selecting and moving rows of pipes without also moving the entities in the same tile row (among other stuff). It was a very nice "smart" QoL feature.
However in 2.0 selection drag tool was made to use entity's selection box which now forces the selection of all entities in that tile row, making it impossible to pick only the entities of the same type.
