Ok, I will add it to the normal actors then. I mainly used the highlights because it is easier to update the object after each interactive action (calling removeHighlight instead of removeActor with the specified actor).

Why do you want to add to the highlights? Can you not use a normal actor instead? The highlights are mostly intended for picking operations.

If you need it, experiment with it, and if it is useful, make it a configurable change. I am not sure, but point and edge highlights may come out bad if they are not drawn first. If I remember well, that is why they are treated separately before drawing the other actors.

We may add some feature to let the user influence the order of drawing. E.g., sort the actors by there alpha value.

I have a function to manually determine the best-fit sphere for a certain geometry. During this interactive function, the sphere is redrawn each time the user updates its parameters. I would like the user to be able to switch between normal and 'ontop' rendering of the sphere. However, this is not possible if the sphere is added to the highlighted actors because these are drawn before the scene actors in the Canvas.display function. Would it be a good idea to change this, i.e. to draw the highlighted actors after the scene actors?
