Has a client ever asked if you could reorder or change the name of a tab. Instead of displaying the view, edit and revisions tabs, the client wants to move "revisions" before “edit” and rename "view" to "current". This can all be archived by writing a custom module and implementing
hook_menu_alter, but there is a module that allows site builders to rename, reorder, disable and hide tabs. It’s called Tab Tamer.
