Pretty great plugin Danny. Thank you. There is one issue I am running into though. Was wondering if you can help.
Essentially Scroll box doesn't appear as soon as I turn on W3 Total Cache (JS minification). stb div starts at display:none and stays there.
I have tried turning off JS minification and then it does work. However wouldn't disabling JS minification impact performance significantly?
Here are settings I am using currently - http://imgur.com/hzQ56rd
