Hi all,
Disappointed to have no reply about my specific question, but in the meantime I have more or less solved what I was trying to do, albeit without using Andrei's cute "go to full-screen" button in the corner. Here is how I have done it: I hope this is helpful to other beginners struggling with krpano's interface:
I used the defaultskin, but with the controls disabled using
<include url="skin/defaultskin.xml" />
I used the Camera Controls plugin with transparency and a proportional width:
<plugin name="cameracontrols"
alpha="0.5" onover="tween(alpha,1);" onout="tween(alpha,0.5);"
url="cameracontrols.swf"
width="10%" height="prop"
zoom_refresh_fps="10"
keep="true"
align="leftbottom" x="10" y="10"/>
Using a graphic file as a button, I made a "toggle full screen" button with transparency, in the bottom right corner, this way:
<plugin name="fs"
url="../images/black_f.png"
alpha="0.5" onover="tween(alpha,1);" onout="tween(alpha,0.5);"
x="5" y="5" align="rightbottom"
onhover="showtext(Full screen on/off)"
onclick="switch(fullscreen);"/>
</plugin></include>
This gives me a neat move/zoom control, and a separate full-screen control, both of which are elegant and unobtrusive.
Here's an example:

Thanks krpano AND Andrei for great products: I'll change all of my QTVRs to be this way.
Regards to all (suggestions for improvements welcome!),
