I've just DL'd the new ao3-saved-filters and it is doing it's pre-loading thing! I like it lots.

I don't think tumblr savior *is* being developed as a userscript anymore? I have it as a chrome extension (along with missing-e because together they are the PB and J of my tumblr bread if that metaphor makes any sense)

But it looks like in the four days since I last checked up on this thread (>.>) you have played around with savior-esque-ing up your code. Cool!
