Adds buttons for various channel playlists: Play All Uploads, Videos, Shorts, Streams, Members-Only.
AP toggle adds playnext=1
to URLs so the first video in the playlist starts playing automatically.
NT toggle adds target="_blank"
to URLs so a new tab is opened on click (same as mouse wheel or middle button click without NT).
Works only for Desktop website (not m.youtube).
Inspired by YouTube Play All script by Robert Wesner.
List of added playlist types (see here and here for documentation): UU, PU, UULF, UULP, UUSH, UUPS, UULV, UUPV, UUMO
Note: if the script doesn't work for you, try also installing YouTube TrustedHTML Bypass
