This is really handy and has a good set of options for fitting into whatever way you like to browse. You should absolutely give this a try, and open the options panel if it doesn't suit you out-of-the-box.

The one extra thing I'd like to see is an option to have settings like "ignore path" apply to particular domains only -- I'd love to be able to open four articles from the same website but reliably collapse four instances of the same web-app.
