I personally prefer to pin page menus. Every time however I have to delete cookies, change browser, or change PC, all the menus I have pinned are reset to the default position of 'unpinned'.

I would be a nice touch to be able to pin all menus in one go, either with a control stored against the user page, or at the point of pinning a menu, having the option to 'Pin this menu' or 'Pin all menus'.

This way you are not forever re-pinning menus.
