I am using this feature I think that the "rename..." menu option
should by default work like refactor, at this moment it just renames
the class with updating dependent stuff, if you want to apply
refactor you have to drill down to the refactor class suboption.
I think "remove class..." and "rename class..." (in a refactor way)
are the more frequent actions applied on a class. I don't mind if
the option is duplicated in the menu if it makes thing easy.
