Is there any inherent advantage in designing an App in Excel with custom
menus, toolbars, worksheet data validation, taking control of the UI from
the user etc etc? To me, it appears to be a wasted effort with more time
spent keeping the user away from the UI of Excel than developing program
logic. However, I am aware that this has/is being done. The Apps I have
seen with this setup seem to lack a 'professional' look and feel. What is
the logic behind selecting this setup?
