This is a very cool addition!

I played around a bit and noticed a few small issues (without looking at the code just yet):

• The right-click context menu and the Display Options are not in sync, this is especially apparent in the transparency slider. Using the one from the Display Options doesn't update the one from the context menu and vice-versa.
• The context menu has one more rendering mode compared to the Display Options (textured)
• When I have the tab "Display Options" open for one CPACS node and I select another, the tab "CPACS Editor" is open. I would expect the selected tab to persist and I see the display options for the newly selected CPACS node.
• Feature request: Can we add a button "Reset to default" to the Display Options of each individual CPACS node?
