Another way would be to be able to specify a predicate function to do
the filtering.  The function would be passed a record and would return
true or false to indicate whether or not to include it in the menu.  You
could define a couple of standard functions (which would be able to be
called from within user-provided functions) to do common things (e.g.,
to do the sort of filtering that t or nil would do).  That way the
apps-menu-display-all would be simple to use for novices (it could still
take options like t and nil) but if its value is a function (or even a
lisp form?) instead of t or nil that would be the predicate used.  If
you wanted, you could even get a bit fancier, and allow the function to
modify the record (i.e., the function would return the record, possibly
modified, or nil indicating not to include it).  That way a power user
could, e.g., rename certain entries or maybe even categories easily.

Just an idea; I don't know how easy it would be to work this into your
current system.
