I use "classic control bar" on the panorama. But the button to close the bar is just a square. Normal Japanese people would't know how to close the control bar. Yes, if I put the mouse control on the button, it says "close buttons" (tooltips) However, I need the information to close the bar without putting the mouse controls on it. What I want is to make a text button and when you click on it, just close/open the bar.
I would suggest a toggle button: State A: you give the action "hide tour controls" with the corresponding text as a PNG State B: you give the action "show tour controls" with the corresponding text as a PNG you have to unselect the "Respond to show/hide controls request" for the button and select the "Respond to show/hide controls request" in the control bar
You can also add a skin to the control bar, replacing the icon for the show/hide controls if you can think of an icon that would be more understandable for your clients.
