+1k. Don't need anything else. I think the simplicity's a mental hump for many, as I don't get why it's not more popular.
It currently does everything except calendar dates/notifications, which I'm currently working on adding to my User Script. (Shameless plug: http://workflowier.com/)
I couldn't keep up with the complexity I layered in to it, so I'm building a webapp to do the mind mapping and translations to a to-do 'now' list. My biggest need was a dumping ground for all the things I knew I should be doing.
My brain is much quieter now.
