Halfcomplete? Rated 3 out of 5 stars

Does its job nicely, - BUT: you have to have the add-on toolbar open to pick up the icon in the bottom-right-hand corner. No tips to guide you, and no way to save the image out. So it comes across to me as a short-term novelty, rather than a genuinely useful extra.

This review is for a previous version of the add-on (0.2.1.1-signed.1-signed).
