What is MAL Updater?
An anime 'scrobbler', auto-updates anime on your list at MyAnimeList.net when you watch it on your computer.
Includes various plugins, including one which downloads new episodes of series you are watching when they become available, via torrents.
It can also be used to keep track of manga you are reading, but this must be done manually, for probably obvious reasons.
