Might be one of the best extensions I've ever installed. Works great.

I'm using this to solve two problems:

1. "I looked this up once, where was that? What did I search for? Can I find it in my history?"
2. "I should re-read this for the next few weeks/months to reinforce what I learned."
3. "It would be great to capture the Reddit/HackerNews discussion thread along with this article."

Oh that's three. I lied. Oops. :)

My filename template is {visit-year-utc}/{visit-month-utc}/{datetime-iso}-{page-title}.html. This lets me easily identify pages from the previous month, which I then can review and update as needed. Generally I find things through Reddit or HackerNews, so I annotate the page with the post URL. That context comes in handy.

Would be nice to be able to save pages to a custom path in the filesystem. Tags would be a useful addition as well, though it's pretty easy to just do a search in the filesystem for relevant content.
