Lurker's Guide to Babylon 5 PWA
(All About Windows Phone)

It`s a fair cop, this somewhat minimalistic PWA is essentially just a mobile web site, but a) it has a facility to toggle whether you`ve viewed each episode or not (and remember this, at least on a single device), and b) it remembers with great comprehensiveness one of the stand out sagas in TV science fiction (in my opinion). Anyone else a B5 fan? PS. The name `lurker` comes from the nickname of drifters within the B5 world, I think!
