Very Nice- might not work with other add ons Rated 5 out of 5 stars
At first I could not get it to work. but then realized that several Google Labs extensions were interfering. not sure which caused the problem. "inbox preview" or "preview pane". I really liked those two, but I also like this add on. damn. when those are installed the collapse window is too small and nothing shows up.This review is for a previous version of the add-on (18.104.22.168-signed).
