Serious sync issue (MacAir / iCloud). If fixed it meets 5 stars for sure.

Please fix the problem with sync. When Due is running on a few gadgets (iPad + iPhone + MacBook) sync starts to fail.
Only reboot of all the gadgets can help but it is dumb!

Another thing is to add auto-sync for new notes, not only on start/quit of the program.
