As I've been playing around with pre-release versions of iOS 8, and saw the hiccups of Take-a-Note, and played around with other applications, I tried to remind myself why do I need TaN? Why can't I use other applications? What am I really missing from (for example) Notes, Reminders and others...
So I started this list:
* Clear indication of items waiting
When managing a todo list, I need to quickly see if (and how many) items need handling.
My notes are not my long-term memory - but my short term memory, which I expect to later convert.
My TaN solution for that was badges on the app...
Any other app _must_ have this.
