I found this topic about reference notes. I need this too. What's news about this?

"I would love to keep some notes just for reference in doit.im. I am aware you are considering a way to integrate to Evernote (which I applaud and would use). Another option would be to include a new "box" called Reference. In addition to the boxes for Today, Next, Tomorrow, Scheduled, Someday, and Waiting, a Reference box would let us track Reference items separately from timed, next, or someday actions.
