This is a small script to extend the hide/unhide Editable_Poly options out of an object to help in its visualization when you need to have the object unselected or freezed.
-Create a group of faces of an Editable_Poly mesh
-Add more faces from the same mesh or a different Editable_Poly mesh
-Remove groups and remove faces from a group
-Rename the name group
-Order the list of created groups
-Save and load the groups created in a .txt file
-Open more script windows for different needs
Tell me if you think it's necessary to add more features.
Hope this can help in some way ;-)
