Hi,
in my opinion it would be a really helpful, when the 'user privileges' tab on the process is displayed in red if any form type privileges are defined.
I would use the color red as it's used in other cases, where the inheritance is broken like with forms.. Even so this is not strictly inheritance with the user privileges it will help to realize that there may be different settings.
In my case I came back after my vacation and was wondering why the hell the customer could still work also no privileges had been defined on the process. They did exist before my vacation. It took me longer than I like to admit until I thought of form type privileges. After I realized it I remembered a discussion that they may be moved from the process to form type level.
Best regards,
Daniel
