Filterize is a powerful add-on of Evernote. I have over 10 newsletters and 2 data charts sent to my Evernote daily. Filterize automatically adds tags to these notes, making it easier for me to categorise them for later use. The Eisenhower Matrix script Enrico wrote is working like a magic. It turns Evernote to a GTD tool or even a project management tool. There are so much potential that Filterize and Evernote together can do.
