The UID's are a must! I use them constantly to tweek, remove, etc. POI's. Not once have I thought it was tacky. In fact, when I saw that it was included, I said, "Sweet! Man, that Quib is un-stoppable."
One thing that does bug me though.. If the EQ2Updater cannot update for some reason, it will not allow me to launch EQ2 anyway. Why the heck should I be stopped from playing my game because my POI's are not up to date?
