Only slightly offtopic: Here's a similar use-case and how I solved it. The problem is 'collecting' job ads efficiently to spend my time applying for.
Requirement: Avoid redundant re-reading of the same stupids ads over and over, (so alway view ads boards by date, most recent ads first; and maybe use 'email search by date filters' too). Also, I want to avoid applying with recruiters as much as possible by applying only directly to firms whenever possible, etc.
The Scrapbook extension allows me to quickly select html verbatum from any web page and save it locally to disk with my notes, while a right-click takes me to the original web page. I save these in 'dated' folders, at least initially to save time, so I can stay focused to the task at-hand. Even when the original webpage is gone, I still have a copy of it, (and I didn't print or save any paper either).
Scrapbook allows me to save these pages locally to disk in folders, *and* the extension appears in the sidebar, *and* allows me to prioritize the ads worth applying to simply by re-ordering them up and down, using the mouse; and also move them to other folders
This is the best solution I've found so far, and if anyone knows something better I'm eager to read.
