Hi Marc,

> Maybe tiny lightbulbs icons to indicate visibility would be in context!

I thought about that. But there are some problems with that.

The biggest one is that I think it would be easy to confuse with "selected" - a yellow lit up bulb looks kind of similar to the selection color and I think could possibly be misinterpreted when just glancing on it to mean selected/unselected rather than hide/show.

I think the lightbulb comes from AutoCAD's layer browser?

It actually seems to be a lot more common in general for programs to use an Eye icon to show "show/hide", in 2D illustration that has been the case for a long time with layers in photoshop. I had checked through a few 2D illustration / photo apps and I didn't find any that used the lightbulb for that, most use an eye and a couple use a checkbox.

The other problem with a lightbulb is that MoI's program icon is also a lightbulb, possibly leading to some confusion there as well.

Another idea was to maybe show a shaded sphere to mean "show", but I'm actually pretty happy with how the eye has turned out.
