It would be very useful, in my experience, to allow users the option of
saving a draft of their journals during the writing process.
Many times I'll want to write long entries, or I'll have a half-formed plan for a
journal entry, or want to support an entry I've written with facts not close-
at-hand, or be moving around during the day and only be at a given
computer five minutes at a time. I believe being able to save what I have
and come back to it would be a feature that really helps facillitate writing.
I envision being able to open a draft and save it again as a draft (hence
updating the saved draft).
