--I have managed to solve most of the issues that were
preventing a live demonstration of applets layout
during InConfigureApplets mode... Things are more
intuitive now are updated correctly between different
layout areas... enjoy...
--container fill calculations are now tracked much
better when they are applied.
--as an improvement fill calculations are now taking place
at all edit mode states. So inConfigureApplets mode
the fill(s) applets do not throw out of screen
applets that are the layout edges
