Rated 2 out of 5 stars
Sorry, but it seems to me the developers have just been crazy since their excellent 0.8.9 version! Neither 0.9.0 NOR 0.9.1 do work correctly: 0.9.1 totally ignores my next/previous hotkeys (ctrl+right arrow/left arrow). I had to roll back to 0.8.9 again!!This review is for a previous version of the add-on (0.9.1). This user has other reviews of this add-on.
