Systems & Acronyms - is not required to know what Playlist names mean. The applied "tags" have their full names in the Playlists description.
Channel History - is used to record major events, whether this is an overhaul, or 10+ videos being removed from 1 playlist in 1 day.
Playlist History - is much as it sounds. ONLY covers "[T-VI] [MAP] [∞]". I simply don't care enough about the rest to record those as well.
(All of these will eventually get compressed down to 1 Index document to save space here.)
Other Playlists - contains playlists not directly related to [MAP] [∞].
