Side note: not sure if I just haven't been paying attention, but I noticed the slider pagination (with option to click one page at a time) and thought it is really neat. Is there a reason why this isn't more of a thing in UI design? Would it make it 'too easy' to navigate to different pages, and increasing database queries?
