Dialogs should remember values entered when once used. For instance: "Resize to fit contents" page dialog always defaults padding to 0.

The same could apply when some element is added, the color, font and shape could be copied from the last element of the same type changed.

For instance if we add a Baloon and change the Opacity and color, the next Baloon element added should have the same Opacity and color as the previous one.

This would help ensuring the same look and feel on the page.
