Just in case anyone hasn't figured this one out yet you can indeed import your Note/Note2/Note 8.0 notes into your Note 3. To do so, of course, you'll need to be synching your notes with your Samsung account on both devices. Then...
1. Open S Note on your Note 3
2. Click Recent Notes in the upper left-hand corner
3. Click the Menu button and select Import-->Samsung Account
4. Select the Notes you want to import or choose the Select All option, then click Done
Your Note 3 will show "Importing" as it concentrates on the task but when it's done, Voila!
Why this is hidden this way is beyond me but at least it works!
