I’d like to be able to change the way that the overview rectangle behaves so it works more like Photoshop. Specifically:
- The shape of the rectangle is proportional to the shape of the observed document’s view.
- The size of the rectangle is controlled by a zoom factor - either the mouse wheel or a zoom factor control.
- Anytime the mouse is inside the rectangle, the “move” cursor appears and the user can drag the rectangle around using the left mouse button.
Any hints on how to do this?
