I like the site but the map at the top of the search, can that be collapsible? It feels very suffocating; I don't care about the map but I have to have it take up ~50% of the screen with the results (what I do care about) listed below! Also when updating the filters it's so fast (yay!) that the "loading" screen flashes up for only a few ms so it appears like the screen is flashing black. And my final thing: if you view a listing via the search it should give the option to "go back to search" without needing to use back. Other than that it's great!
