[MAJOR] Almost all hidden properties are now disallowed, they have been allowed since UEFN released until 34.30.

@Kev.EG I would like to re-iterate one thing from the previous requests. Is there any chance you can expose “Is Editor Only“ or is another team in charge of that decision?

In fact, that setting is already partly exposed.

When we create a new prop blueprint there’s an editor only static mesh component. Copying it reveals two settings:

bIsEditorOnly=True
bIsVisualizationComponent=True

Any chance we can get these exposed? bIsVisualizationComponentseems to be restricted to only appear within a actor blueprint and it causes the component not to leak into the details panel when selected in the outliner.

bIsEditorOnly is theoretically available everywhere.
