I would like to avoid saving multiple references to same entity. so some method comparing them would be nice. ID mayby?

-methods like findentities and getselected always create new table for entity. So can't use reference number.
-some entities can be stacked. so position is not fit for all cases.

as a workarround you can try to move it/modify it some way, then compare that thing, then move it back, and compare the original position.

There is method equals. It checks if those references point to the same entity.

@ficolas
