I'm using the gyro option so only need the button on hand held devices, was wondering if it's possible to set a button to only appear on certain devices? I'm gonna assume if possible then it will be in the .xml
By default tours created with PTP only display relevant/appropriate control bar buttons/icons depending on teh type of platform used to view the tour.
Most control bar buttons/icons are not displayed on multitouch UI devices.
Likewise the Gyroscope button/icon is not displayed in control bars on devices that don't support the gyroscope function.
