Nice efforts! But pretty disappointing to see these efforts being limited to "mobile" devices. "Mobile" devices are perfectly normal computers, just with a smaller physical screen. Also, there's no boundary between "mobile" and not mobile devices. Smartphone <-> tablet <-> laptop <-> desktop is effectively all the same, just with growing screen sizes (what about a phone connected to a large desktop screen? What about desktop users using a small window?).
Very obviously, desktop users would benefit from all these enhancements as well, so please remove this artifical distinction. Wikipedia is one community!
