Totally agree - being able to not only list things from top-to-bottom but more visually seems to work far better for me as well (though I suspect people's brains may work differently?)
My love for outlining like in Workflowy or org-mode but my need for more visual-based tools like Scapple or mind-mapping is what led me to scratch my own itch and create Mindscope. It's an attempt to be the best of both worlds. Would love feedback, of course... http://www.mindscopeapp.com
