Hi,
I’m afraid at the moment there is nothing we can do about that. The plugin tries to calculate overflowing elements, but in most cases these are simply undetectable, so there is no offset.
The good news is, that the next release is almost ready, it will be out within 48 hours – and there we already added an option to set a +/- offset to these scrolling features. Then adding a positive value will scroll the window further down.
