Hi,
Shelve to automatically archive all of my bookmarked links, in order to make snapshots of sites of interest through time.
What exactly are you trying to achieve? Monitor site changes? Maintain a history of snapshots to document a webpage's development?
I think too that there are better ways to do either than using your web browser. One exception might be javascript-heavy sites that don't render anything useful when downloading them with, e.g., wget. I personally would be surprised if there weren't any apps around for your use case. I don't think this should be done in your web browser though.
Regards.
