Nice summary of everything you need to know about saved variables.
A few things though:
- I created this wiki page on how to find the user folder (addon/saved variables), so we do not have to write yet another explanation that won't ever be updated again when something changes. So please link to it instead of writing that it is simply located in the documents folder, because sometimes it isn't.
- Closing the client with Alt+F4 or the [x] won't save your data as it just kills the process. At least it worked like that when I last checked.
- You should also mention that recursive references are really bad as they will fill up your disk and then crash the game.
