One problem I see with this is that if you have a group of objects, then where does the group go if one object has "always on top" while the others do not?But I do agree that there must be something obvious about an object's placement when the box is checked.I would love to see a visual representation of some sort. Maybe highlight the object with a light gray. Maybe change the font to blue. Maybe put an up arrow over the object's icon.I feel it is important to identify what objects are exceptions to the stacking in the nav pane. Allowing us to do this would be a great improvement.Kevin
