I haven't posted yet, so I don't feel too guilty adding to a thread that's just too long already.

GTD purists, why haven't you been beating on the OF developers about flags? The Book doesn't mention flags. They aren't GTD. Should we have a new war about the blasphemy of flags? Just kidding! Just kidding!

I want priorities for the reasons GeekLady posted so well. Flags seem like binary priorities, so it might be natural to replace them with 1-5 priority levels. Some people will still want flags, so perhaps OF should let us turn on or off both flags and real priorities. There may be a use for both at the same time. Make today's behavior the default.
