If you have used the "New Note" feature in Mail.app, then you may have noticed that the feature is gone in Mountain Lion. Although I was generally happy with the new Mountain Lion features, this completely disrupted my daily workflow process.
I used the Notes feature to create pseudo "Tasks" as part of a GTD type of workflow. This allowed me to keep tasks and email messages in different folders. Even though the feature is now gone, I found that I am still able to do the same type of thing with draft email messages. For example:
- Create a new email message
- Leave the recipient list blank
- Give it a subject like "Task: Do this and that"
- Type in some instructions in the email body
- Save the email message as a Draft
- Move the message from the Draft folder to some other folder, like "Today"
The only problem was that I wasn't able to edit the messages after I moved them out of drafts. As a workaround, it can still be edited by moving it temporarily back to drafts.
