The pushpin info box is a fixed size, which can be problematic when viewing tours in devices with small screens, or in small embedded areas. It would be great if the pushpin info box size was calculated as a % of the total view area, to guarantee that the complete pushpin info window will be visible, without obstucting the viewport. Maybe there is a setting to modify this already, and I just haven't found it?
Thank you for the feedback. We added it to our feature request list. We will let you know when it's ready.
