Signing in with a Plex account
Anybody who has access to your library anyway signs in with their Plex account — no second password, no second invitation.
It is checked against your server's own identifier. A stranger's Plex account with no relation to your server does not get in.
The connection itself is a one-off: sign in, pick your own server from the list, done. Nexview remembers the first address the server actually answers on — the local one comes first but is not always reachable from inside a container. Silently storing the wrong one would surface months later.
That makes a mail server dispensable. By default Nexview creates an account for every unknown Plex sign-in — with the role you set as the default, and without automatic approval. Anybody with access to your library is in, with no invitation and no confirmation mail. If you would rather not have that, switch the import off in the settings; then invitations apply again.
It knows what is already there
Nexview reads what sits in your library and so also spots titles that never came through Radarr or Sonarr — copied by hand, part of a collection predating the arr setup, however it happened.
Such titles show as in library and cannot be requested a second time. Without that, the most annoying case is guaranteed: somebody requests a film that has been on the disk for years.
The sync runs hourly in the background; the settings show how many titles are indexed and when it last ran. A button triggers it at once — and reports the error in plain words if it fails.
Your Plex watchlist, in here
Whatever you have put on your Plex watchlist appears under Profile → Manage watchlist as the same tiles you know from the catalogue — with the same badges, including already downloaded and 4K.
A filter separates everything from not here yet. That second list is the reason the page exists: it shows what you have marked but not yet fetched.
A click opens the usual request dialog. Quota, approval, block list and age limit apply there exactly as everywhere else.
Nothing happens on its own. No background sync that requests of its own accord — every title takes a click. An administrator has to enable the feature in the first place; it is off by default.
And what you have already seen
Titles you have already watched on the media server carry an eye — and everybody sees only their own.
For a long time that was reliable for one account only: the one whose Plex access sat in the settings. Everybody else was read from the playback history, which Plex caps at around 500 entries — and which never hears about titles ticked off by hand.
Today every Plex sign-in stores that person's own access, and the sync reads the complete state from the library counters. Plex has the last word, in both directions: remove the checkmark there and the eye disappears here. Except for titles that have left the library — deleting a file does not undo having watched it.
Plex only, and all of it optional
Nexview currently supports Plex only. Jellyfin and Emby are intended but not there — anybody running those can still use Nexview, just without these four things.
And all of it is optional. Without a media server you lose the Plex sign-in, the in library marker, the watchlist and the watched eye. The rest — discovery, requests, approvals, calendar, notifications — runs unchanged.
