There are a huge number of ICON used by Plex, both in the Web UI and on my IOS player. How do I find out what EVERYTHING means in these different UI’'s? For example, on both the Web APP and on IOS, there is a small green padlock next to the name of my media server library. What does that mean? Can I change it’s state? If so, how? What does the little “eye” ICON mean when I view details of individual movies in the library? Obviously this would seem to mean Watched or Not Watched; but which is which? Either way I try to interpret this ICON, there is wrong information conveyed. It would appear to be in an “On” state for movies I have clearly NOT watched (a movie I just added to the library!) and vice versa.
Finding any of this sort of information in the on-line docs is pretty much a joke, IMHO!
