Hi,

I understand that you are proposing to extend the 'profile' notion to
menus, so that a menu may have several profiles, each profile having 
its own set of conditions, along with its own set of subitems.

I suppose that, as for actions, only the first valid profile, regarding
the currently selected files, will be considered, thus determining the
current list of subitems.

I am not really convinced that this would simplify the spec
(after all, we are adding here another level of somewhat as an
indirection), nor the implementation itself (but this is rather a 
point of detail).

If I agree that this seems bring up more potential to the spec, the only
benefit I see is having different menu order in different conditions. Not
sure this will be a great benefit for users (and I thought that dynamically
changing order of items in a menu was almost always forbidden by human-
machine interface specifications ?)

Do you have envisaged another sort of use case ?

Contrarily, I am afraid this will not help us for debugging when a user
will complain that "my action does not appear in the menu"...;-)
