Way too many updates and fixes is why I still go the route of external HDD clones via carbon copy cloner. Back Up User Prefs is beta material. Developer, you keep finding new problems to extinguish; your work is incomplete. As interesting and useful as this application appears, I just cannot see dealing with the daily changes. Before I add anything to my systems I look for stability. Fixing a preference problem directly, or with a complete HDD restore via CCC, would take less time than to download and install all these updates. Waiting for a steadfast product.
