How about adding a "special" group called [Favorites] or something like
that which can be used to manage the favorites?

Hmmm, no that would be silly, better the other way around: why not
change the EPG so that it knows about groups?
That way it could be made to show only the programs from one particular
group (which you can change of course).
The ? could still be used to add/remove the currently selected channel
to/from the currently selected group.

Would be easy for families as well: John's Favorites, Judy's Favorites,

But probably this is exactly what you had in mind anyway, isn't it? :-)
