The idea is good Gargoyle, however as Jochen and others say the implementation and continued management is a LONG thankless task that I doubt anyone wants to spend that much time on. Many of these UDFs could/would possibly fit into multiple categories so then what? An arbitration council? Then each one of those in question would possibly take from a day to a week to agree upon (if at all) so if say 100 UDFs fell into that category it could potentially takes months to even get to an agreement point for all of them.

ScriptLogic doesn't have that issue because from what I can tell there is one person in charge so it goes where he says and he is PAID to do it
