Alright, there's one more thing I'd like to say, feedback wise.

If I add a webpage, and that webpage changes url, or gets removed for whatever reason, that page also automatically seems to get lost in collections.me - adding a snapshot/saving of that page on collecting would be great.

I also tried doing this for an image on my server. I removed the image, but I still see it (which is good). I wonder however if the image has been saved, or if it's just a cache in your webkit viewer?

Ps. Please don't take all my feedback as negativity. What you've built is a great start! Well done.
