Often in the menu name we repeat the parent name like for Sales / Configuration / Sales Configuration. This is because the name of the tab will be only Sales Configuration. But this implies that the menu names are overly long just because they must work alone.
I propose that the tab name become the full name of the menu used to open it. This way we can just use Sales / Configuration / Configuration. But also as we often have a folder and a direct entry with the same name, we strip the duplicate. The example will have as tab name Sales / Configuration.
