I'm currently using this plugin. I think it works awesome! My only question is if it is possible to set how aggressively the content is shown. Since I have a responsive website, I would like to set this aggressiveness depending on the width of the viewing device.
For example, if the device is a mobile phone, show new content when user has about 800px to the bottom (because my sidebar is in the way), if the device is a desktop, show at around 500px, etc.
Does this make sense?
