Hiding elements currently also excludes them from transforms, but that is not its main function. Calling "hide", followed by "show hidden" just feels a bit makeshift I think.

"Show all" would reveal back the entire body, and hiding those specific vertices may not be ideal.

	This is what I often miss when working on complicated models. Just pin some geometry and still be able to hide/unhide parts of a mesh as I want. Ability to use pinned verticies for cursor positioning is also could be useful in some cases. Pinning and hiding are different things. Option to "show all" hidden geometry is better than nothing, but it will not replace pinning in many cases and will be just another counterintuitive workaround. So I would like to add my vote for pinning. Thank you very much for working on it.
