Rated 5 out of 5 stars

I love this extension, thank you for porting it to TB3. :-)

For those of you who have unreadable white text on the yellow notes (e.g. due to a Thunderbird theme like PitchDark, which uses white font color), I figured out a fix.

Add the following to your userChrome.css file (in TB's profile folder (see http://kb.mozillazine.org/Profile_folder_-_Thunderbird for info on that), there in the subfolder chrome - create file and folder if necessary):

/* Xnote - set text color to black */
.boite-de-texte, #titre
color: black !important;

This will set all text in the notes boxes to black.

Hope that helps.

This review is for a previous version of the add-on (2.2.0).
