Rated 4 out of 5 stars
it's interfering with scroll bar when using it on the right-side with auto hide option, but it doesn't hide completely. and I've to click on options to reset it.
Some other users also indicated this problem.
P.S. OK it's solved... I cleared the check box "with borders" and now it's working fine!
So changing rating from 3 stars to 4!
I'm add-ons grabber, so it would be great if I see a scrolling or multi-column option. worth 5 stars!
