Version 10 is a joke. Nothing what I used to use is working:
- No Sync button (and it is not syncing).
- No Export of all notes (i.e., no backup).
- Filtering by tags - not working realtime (I remove tag, the note is still in the list)
I am starting to search for another note taking product (again). It looks like any change in Evernote is for worse.
For now, I recommend to anybody who cares about his data to go back to version 6: https://cdn1.evernote.com/win6/public/Evernote_6.25.2.9198.exe
