It's been a day and I've now moved "Unlocker" into my keeper list.
Tried to download an audible book, but the audible manager is a POS so even though I'd closed it the partial downloads (that I had just canceled) were "being used." Unlocker made quick work of that and I was back downloading within seconds.
Google customizer is cool, I think I'll keep it, but I'm not sure I'd even notice it if it was gone (not yet anyway).
