+1 as well. I want to be able to record everything I need to do with dependencies so that I (or whoever is doing the initial tasks) don't forget to add them later, or so that I don't have to look for them to change their status after the first one is done. For instance, "to go post office" becomes active after "package up boxes" is complete.
I see a reference to "tags" in the help section, but it says nothing about how to tag tasks or how to get to the "tag view" that is referenced or how to see your tag cloud. Am I just blind? A little help?
