The $InteriorScale is a very useful and helpful feature.
Is there a command like this one that fixes the position of a containment element that is transparent in the Container?
I find it slightly annoying that the position of the content that shows through is variable when zooming in and out on the entire map. 
Look at $MapScrollX and $MapScrollY and here.
Using those will control what you see on the container map. It does not affect ‘where’ on the child map the view centres when you drill down (or up!). The latter’s logic is as yet accurately documented—many report inconsistency of results so the underyling logic (there will be one!) is yet to be captured.
hi, mwra.
thanks for information!
I’ll try it!!
