Subject: [PATCH] Added option to unhide all faces of a object
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This option was missing and is useful when we need to temporarily hide faces
to work inside an object. Without it, unhiding becomes complicated since it
requires repeatedly selecting adjacent faces to close the entire object.
The new option simplifies this workflow and improves usability.

NOTE:
Added an option [MMB] to Hide command allowing unhide all faces. Thanks Flüfy Nũrbs
