Designer "collapse to code"

[Mistrel]

Although the designer is very nice it's hard to work with overlapping controls. It would be nice to have a feature to collapse individual controls to code and even whole forms. This way I can continue to work with the designer to create complex forms without the interface becoming cluttered.

You could increase the form's screen size (desktop only).
Arrange your controls inside panels in the large area.
At runtime change the panels position / visibility and show the relevant controls.
