How to find about all the ICONS used in Plex Web APP and Plex on IOS?

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!

Little “Eye” icon toggles the state - look for the little orange triangle icon: https://support.plex.tv/hc/en-us/articles/201018487-Mark-as-Watched-or-Unwatched

Positioning your mouse pointer over these icons (but not clicking) helps a lot.

This is actually a Yes and No! Yes as it applies to the Web app UI; No when it comes to the IOS ICONS, since there is no mouse-over & hover capability. Oh well, overall I can see the point. Guess I will just have to hover over everything in the Web UI and see what shakes out.

Thanks.

You might as well take a look at the documentation:
