Rated 5 out of 5 stars

This is awesome. Was using QuickFox for notes. It's functional but this slaughters it like a shotgun handles zombies.

I hope that this continues to grow into a powerhouse of functionality.

A few notes:
1. There seems to be an issue with it keeping the cursor location when using the format toolbar
2. The editor doesn't seem to respond to typical keyboard shortcuts such as CTRL+B for bold
3. Can you setup the tags to no highlight the background of the note and rather highlight the note info in the note pane (if that is what it is called) like is done with McTwists userstyle or like what TagToolbar does as well?

This review is for a previous version of the add-on (0.9.18).
