I suggest making it possible to search for specific items in the achievement search section. Both items needed for achievements and achievement prizes. This could also go for achievement titles if so inclined. But really, want the items to be searchable, not just the achievement title name itself.

God yes! There are times when I've wishlisted something I need for an achievement. Acquire the item months later, but then have no recollection of why I needed it.

The ability to search for prizes (including titles) would also be very helpful.
