Would love ability to filter even more in the Feeds

The feeds currently are great, but as some forums get more popular, I've noticed that I'd love to remove certain forums from the feed at times or choose multiple forums to see their feeds all at once.

For example, I love Post Loop, but the feed is filled with the activity there. I do go there to post at times, but I'd love to be able to filter it out and get to the smaller forums to save some time and help them out too by posting. Doing it one by one is slow, so maybe in the future I can select from the drop down multiple forums?
