1. exclude chrome:// and about:// URL's
2. Not sure how, but it would be nice to one-click restore an item from Trash back to where it was. Alternatively, perhaps mark in-place instead of moving to Trash? Then it's easy to spot them and manually remove. Also I got quite a few false positive sites with valid certs etc. Increase timeout perhaps?
3. this might be impossible, but I wonder if there is a way in chrome to download /favicon.png without opening the whole page in a new tab.
