it's amazing how many project management tools allow you to rate your priorities...but what does that really accomplish when you end up with 90% high priorities? you need to go a step further to differentiate the priorities. that's where listing (AKA ranking) can really come in handy. we actually took a hard look at leveraging our ranking software from http://gorankem.com http://gorankem.com towards a PM play...but the space is just too saturated. one of the existing players needs to add a feature to prioritize within the (high) priorities anybody know of a PM tool that may do the job?
