- Only "option" is ability to change color of each note individually. Can't adjust globally/default, can't adjust font size, make toolbar icon create new note when clicked instead of opening menu (menu could be accessed via right-click), etc.
- Every time a new note is added, it's added slightly below and to the right of the last note, so you can't even set a position and have that be a default.
- Clicking off a menu should close it instead of requiring clicking the x button.
- List stickies doesn't work.
- There should be a notification when a sticky is off-screen (when you have to scroll to see it), as with Internotes.
- While sync is a nice feature, I prefer to be able to store the notes locally, in a custom directory, and they should be human-readable so I can always access my notes even if the add-on is no longer available at some point.
- The ability to import Internotes data would be very handy.

There's probably more things that could be improved, but it's clear this add-on won't suit my needs, so I didn't spend too much time with it. It has the potential to be made into a good and useful extension, but currently it is not, at least for me.

Update: Tried again and not working at all. Icon is blank and doesn't do anything, can't even add notes. Shame, since I really want something like this and this one was one of the more promising ones.
