'remember' pano bw/color for fullscreen

I have the same pano, but one in color and one in b/w. You can change them with a button. They are in a low resolution. When you click on the fullscreen button, the high resolution image loads. But how can krpano 'remember' if the bw or the color one was opened when clicking on the fullscreen or the fullscreen-off-button? Maybe with a variable on each pano (onstart="set(bw,off)" or something), but how can I do that?

Thanks in advance!

And another question: how to remember dragmode or qtvrmode or autorotate enabled/disabled when going fullscreen and back (so the buttons are ok)?

Thanks, I'll try!

Quote from klaus.krpano

normally these settings will not change when going fullscreen and back,
but you are saying you are loading a other pano on switching to fullscreen - make sure that all buttons (plugin) that should stay and not be removed or loaded again, have - keep="true" - set,

Beginners mistake. I'm sorry!
What I want works with this code:

<action name="loadNewPano">
           set(filename, 'pano');
           if (bw==1, txtadd(filename, get(filename), '_bw'));
           if (small==1, txtadd(filename, get(filename), '_small'));
           txtadd(filename, get(filename), '.xml');
           loadpano(get(filename), null, KEEPALL, BLEND(1));
       </action> 


       <plugin name="bwoff"
           onclick="set(bw, 0); action(loadNewPano); keep="true">
       </plugin>


       <plugin name="bwon"
           onclick="set(bw, 1); action(loadNewPano); keep="true"
       />




       <plugin name="openfs"
           onclick="set(view.maxpixelzoom, 0); set(fullscreen, true); set(small, 0); action(loadNewPano);" keep="true"
       />


       <plugin name="closefs"
           onclick="set(fullscreen, false); set(small, 1); action(loadNewPano);" keep="true"
       />

And an onstart in every xml which sets small and bw.
