I just signed up to Doit.IM and can't for the life of me find out how to create Filters. On the left column I see the Filters header but when I click on it to expand it displays nothing and I can not locate any "Create filter" or "Edit settings" Am I correct that Filters are based on "Tags"? If so, how do I create a filter based on the created tags so that I can view all tasks related to the tags no matter what their focus?

Thank you.
