Brief - feed reading extension for Firefox

Hi,
I would like to suggest adding possibility to tag rss entries.
I can imagine it working as gmail tags. You can create a tag, lets say "@home" and then when you get a rss entry you can tag it.
To find entries tagged with "@home" you would have to look in a folder similar to Trash or Unread folders created by default by Brief. To folder would have to be created along with the tag.
 
I think it would be a very important change. Many people leave some rss entries to read later, to go back to them later, at home or work etc. With tags working the way I described they can mark it what they want and go back to them later.
Btw. It would be good to be able to see rss channels with and without the tagged entries.
