Error checking on grid config

I have many times run into weird layout problems that turn out to be incorrect grid positioning of child items. I.e. user error bUT difficult to track down.

Eg I have a grid with 2 rows but I paste an item that came from row 3 of another grid. It looks fine in designer but completely screwed up in simulator or Android app. (I have today spent a half day rebuilding a complex page that I couldn’t find the problem on, only to discover it was exactly that type of fault )

These sort of errors can be very VERY difficult to find and I wondered if some checking could be done automatically and warn of inconsistencies?
