Hide the control bar via XML or javascript

Hello krpano enthusiasts,

On mobile, I think that the control bar at the bottom remove too much pano space. So when the pano (vtour) is loaded, I'd like to hide the control bar (but not remove it!).
Which is the XML parameter or javascript call that allows me to do that?

Thanks for your answer Piotr, but it's not working in my krpano version 1.19.

Strangely enough, the control bar gets higher showing the thumbnails of all the panos in the vtour.
