We need some property disambiguation on Page Designer

We really need some disambiguation of what changing options in Page Designer do around whether this is a page-only change, or will actually end up modifying the underlying object that the page is based on as well. This can have knock on effects that people don't expect, when they may believe they are changing something that should only be affecting the page they're working on.

For example, changing the "Title" property shown on the Page Designer will change the underlying entity's field's Title, while the "Lookup view" just below it seems to only change the lookup mode of the field on that page (while there is a "Lookup view" property of the field on the entity, at least when I just tested it, it didn't change). This leads to confusion and caution around changing things to avoid having unexpected impacts, or even worse to unintended consequences slipping through the net.
