Hiding & Locking Redux:

"You can Lock an object and show its wireframe or hide it, but not lock it while showing it with its texture. This third lock mode would be useful. The locked object is fully visible but not selectable, operable or clickable in any way. "

This could lead to confusion when a user tries to operate on a locked object that is not hidden or wire-framed unless the object signals its state in the main window. The obvious solution is to signal this state by a different color for the object's surface lines and vertices, such as red.

Overlapping Vertices:

A single vertex and multiple vertices in the same point of space look exactly the same when, in fact, something different is happening at that location. One way to signal multiple vertices exist at one point is to draw a box around such points. Other methods are a different color (default purple versus blue) or size of displayed vertex. If boxed or sized-up, it could lead to a very busy display when the object is viewed from a distance, which suggests a further operation (cancel at a distance).

Color seems to be the simplest solution and adds a further advantage. When you drag one vertex near enough to another (assuming the suggested-before snap takes place), the change in color becomes gratifying feedback that both vertices are now co-located.

Maybe you shouldn't have encouraged me.
