Rated 4 out of 5 stars

Works fine, just what I needed!
The reason I gave it 4 stars insted of 5 is that I use QNote in my workplace with my coworker. He is on a different PC and we use the same email account. We can not see each others notes. If there will be an update for this, would be awesome!

This review is for a previous version of the add-on (0.10.1). 

You need to use some kind of shared folder for that. E.g. dropbox, windows share or similar.
