Experienced
users (and system administrators) should have the possibiltiy to make changes
to the menus, to cater to user needs (= "adaptable menus"):
introduce/change shortcut codes
hide/delete redundant menu items
move/duplicate menu items into other menus
create links between menus
It does not seem advisable to allow for
completely automatic positional changes in menus, like re-ordering or hierarchical
re-positioning of menu items based on usage frequency (= "adaptive menus")
violates the constancy principle
negative experimental results by Shneiderman
It seems o.k. to perform positional
changes under the control of the user.
