I can't find the settings for this addon anywhere. It doesn't have any options in the add-ons manager, and it doesn't have a button for the toolbar. The blub says it's customizable, how? Seems like that would have been good info to add to the 'about this extension' section. Also, the reference site is nothing but sewing, and the other site the author lists is just about paintball. It's a shame, seems like it has potential to work, but its workings are a complete mystery.
