Rated 4 out of 5 stars
I would like the option to be able to set my own background color (other than "Post-It" yellow).
More importantly, I would like to be able to remove the icons ("T" and "B") from the Add-On bar. I don't want them there. An icon on the Navigation Toolbar is more than enough.
@smed79 ... you can disable/edit/rearrange the context menu entries by using the extension "Menu Editor"
