I have a suggestion to make for the new UI.
There should be another search bar right above the filters for ease of access to search.
There's a logical reason behind it, when I'm looking at the filters my eyes are focused on the left side of the screen, when I want to search for something my eyes start wandering upwards because that is naturally where a seach bar should be. I understand that there's a "search parameters" under the filters, but I think there should be another overall search bar at the top of the filters that doesn't require users to be so specific, especially for non-power users like myself. While we do have the good ol' search bar up top right of the screen, but its "too far" from the filters.
