Well guess what?The tact that not even OP is working on this customization tool anymore tells all, regardless of my opinion.
"It is of my opinion that this isn't a worthwhile customization" Your own words can be used against you. This is their opinion, and it is a worthwhile customization for them, so scrap it. And just cause the OP isn't working on it doesn't mean someone else can't fork it and have it updated.
