Another Menubar idea

First, I'm not against the menubar. I know it has a major importance in the access of all the application possible actions. I just think it does not do it in the best way...

Although it may be often used in many applications (office ones per example), in many others, like the every day use Dolphin, menubar is seldom used and occupies a precious space. This is even more truth in 16/10 screens.

Some apps already have an optional "show/hide menubar" toolbar button, but, IMO, all applications should have an implicit "Menu" button with all the menubar entries in it. I remember that amarok used to have one. This way people can save space by turning the menubar into a little button.

I'm not asking for this to be default, but to be an option, preferably in all applications.

Ah, and please remember: not every app need to have a 'File' as the first entry in the menu!

Thanks for your time.
