My favorite sync feature, however, is that you can sync with both Simplenote a local folder, and you can even configure multiple Simplenote accounts and multiple local folders, letting you store, say, work notes in one Simplenote account, shared family notes in another, and personal notes in Dropbox. Each account or folder gets its own heading in the notes list, with that account or folder's notes listed below it.

A given note can sync to only one location, and new notes appear in the first account or folder you configure--the one at the top of the list. (In Justnotes's preferences, you can change the order of accounts and folders in the list.) However you choose to sync, Justnotes syncs automatically, or you can force a sync by clicking the Last Sync text at the bottom of the window--notes that haven't yet been synced display a small, gray circle to the left. Because notes are plain text, formatting is handled locally, so only note content is synced.

You can transfer notes between Simplenote accounts and synced local folders by simply dragging a note from one section of the list to another. I experienced an occasional glitch with this feature, especially when dragging a note from a Simplenote account to a synced folder--sometimes Justnotes wouldn't move the note--but it generally worked fine. One feature I'd like to see is the capability to collapse an account or folder's section of the notes list to hide that section's notes.

Justnotes provides a number of actions for managing notes. You can send any note, regardless of how it's synced, as the body of an email message or export it as a PDF file. For notes synced using Simplenote, you get additional options: You can mark a note as a favorite (which moves it to the top of the list), and you can add tags to notes; these designations are synced only across Simplenote. Tags are useful mainly in that searching for # lets you quickly view all notes with that tag.

If you no longer need a note, you can right-click (Control-click) the note in the list and choose Archive (or select the note and choose Note: Archive--oddly, there's no archive/delete button in the window). Rather than deleting the note, this action saves it to Justnotes's archive. You can view the archive by clicking the Archive button at the top of the window. This view mimics the main notes view--list on the left, selected note on the right--but lists only notes you've archived. You can restore an archived note to your main notes list at any time. Alternatively, in archive view the Archive command is replaced by Delete, which permanently deletes the selected note.
