I'd like to share an Initiative Manager that I found which I like above all the others out there. It's free a WYSIWYG sort of app, called Initiator (AppStore Link).
I know there are many other Initiative Managers out there, but personally, I like that this is is lightweight and does exactly what it sets out to do.
I really recommend you guys check it out. I think you'll like it a lot too! And best of all, it's free!
