Thanks for taking the time to learn more about Moo.do!
> What is the intended delineation between a document and a top-level header?
Sharing and collaboration works at a document level. I have a separate document if I need to collaborate with someone on a unique topic and have multiple top-level headers in a single document for broad organization within a single topic.
> How are notifications in the app (ios) incorporated. Do they notify based on "@date time" of item?
Each item that specifies a time of day using ‘@date time’ will get a notification 30 minutes before it is due. Items that do not have an exact time mentioned (like 3:00pm) will not cause a notification. [This is not currently working on iOS 8 and we have an update waiting for review.]
> How might this be used as a notepad. It seems like a big aspect of it is the crossing-off of items?
We’ve tried to keep the app as close to just editing text as possible. You can type like you would in Notepad or a Word/Google document with no problems. All of our features are there if you would like to use them but will stay out of your way if you don’t.
> Does @tomorrow turn into @today in the document when a day has passed. Same w/ @today to @yesterday etc?
Yes - we rollover dates that change meaning as the current day change. If you want to ‘pin’ an item to stay visible to you, you could set a priority on the item or mark it as @now or @soon.
We have plans to add additional sources of contacts (and other services) to the app. Having first and third party plugins for adding content and viewing data in different ways is a big part of our goal.
