I've definitely come around to the idea that Theater Views should be different from, and configured separately from, the Standard Views.
I can see why some people would want them to be the same, but navigation in Standard View with a mouse is totally different from Theater View with a controller, and Gizmo with a touchscreen, so I use different views for all three.
Since Theater View/Gizmo behave differently from Standard View, that also affects the views that I use. (Standard Views are crippled with a number of levels removed to improve navigation)
Gizmo/Theater View views are often very similar though, so I'd like the ability to copy views between them and then make slight modifications.
But the way we have to do it now is clunky. I've long agreed that it would be better to do this stuff under Services & Plugins or some other "hidden-ish" area of the Tree.
Yes, I know it's not a new idea, it's just that I got around to making some changes to how things were presented and every time I do, it reminds me how awful the current setup is, since you're making "blind" changes, and have to restart MC every time before you can see how the view operates.
