Sluggish, Not superior to setting a search Rated 3 out of 5 stars

This is a well-executed add-on, but it bogs down when you have many incoming messages. I long ago created pre-set searches and saved as virtual folders, and they reside in the folder pane; if you don't like that approach, this works, but it will also require additional screen real estate -- displaying the Quick Filter toolbar. I think creative programmers should be encouraged and this was creatively programmed; however, it doesn't do much for me. On the other hand, I will be watching for whatever new idea this developer creates in the future.
