I think I may have posted this request in a different thread but this thread seems appropriate too...
It would be nice if when you change the parent of a view (or more specifically, when multiple views are selected like in the abstract designer) that it would retain its Left & Top properties.
I imagine I'm not the only one who later decided to put views on a panel rather than directly on an activity. I tried this once with a layout I had done with over 40 precisely placed buttons and when I changed their parent to a panel I had just added, they all lost their positions.
If you wouldn't want to change the only behavior for this, then perhaps a message box could ask the user if they want to retain the Left & Top properties of the views for which they are changing the parent.
