From the point of view of "usability", it would still be possible to optimise the "Quick search", not only by filtering to one (1) floor (floor), but also by searching for all or which can be individually selected (e.g. floor 1 and floor 2) - similar to how I can select AM and/or PM.
At the moment you have to return to the output filter mask again and then explicitly filter another "floor" (floor).
