The layout is horrendous, the classic theme was far more useful, "search filters" with meta tag ala web 2.x crap is just that, crap. If it ain't broke, don't fix it guys. thanks for forcing it on and killing the old, useful frontend/backend.
Good luck with finishing up the site, its less useful for random browsing now. this new layout is also crud for nonstandard browsers. I'll try like hell to adjust.
