Hi there! Just had a few questions.

1. What does "title" do in the web UI? It appears to re-try fetching headers, favicon, and HTML title for content at a URL -- is that correct?
2. What does "pull" do in the web UI?
3. How about if we added tooltips (HTML title attributes) to the "title", "pull", "re-snapshot", "reset", and "delete" buttons to /admin/core/snapshot/ in the web UI? I couldn't find an existing issue for this. I'm happy to file one and help out.
4. Say I used re-snapshot a bunch of days in a row. Is there some easy way to see/list all the versions I've snapshotted for a particular URL? When I click "History" on the admin page for a snapshot, it says "This object doesn’t have a change history. It probably wasn’t added via this admin site.". I saw Add official support for taking multiple snapshots of websites over time #179 so I'm guessing this isn't implemented yet.
5. Sometimes when I visit the index page for a snapshot, my browser (Firefox) starts automatically downloading an output.pdf file. Why? example archivebox snapshot index page showing this behavior
6. Is there any way to strip ads and trackers? found Architecture: Block ads and trackers during archiving #211 , awesome!

Thank you, -Adam
