I miss the sort by house function too, as I tend to buy more than one fragrance per house. If I like one fragrance, then I tend to want to try others by the same house and end up liking others and buying them as well.
I am not sure if I am using the lists correctly-----I am using the "tried" list for the things that I have tried and the "test list" of things that I want to test, but find the drop down tabs a bit awkward. There is an own, used to own, and want to own. Well, if I own it, or used to own it, then I have tested it already. If I haven't tried it yet, then I don't yet know if I want to own it or not. I have been tagging them "want to own" for lack of a better option. Does anyone else do it differently that might work better?
