Hi Jachym, for me on XP and Firefox 2.0.0.8 this appears quite unresponsive, even though after a bit of clicking something eventually happens. I am not sure about the graphical solution as I do not really know when a layer is switched on or off.
A while ago I experimented a bit with a custom layer switcher outside the map window, it still seems to be working at http://www.yunnanexplorer.com/mars.html There were several ideas in it: First of all ignore the tick-boxes -- they flicker a layer on and off. This is not very intuitive. I thought once having a special effects div hidden with every layer that could be turned on and off. Flickering a layer, moving a sliding window over a layer, inverting colours, image stretching could all go in there. Never followed through. The sliders allow to adjust transparency of a layer: red all the way to the left is off, green is 100% opaque. The rest somewhere in the middle: good way if you want to look at data in more than one map at a time. Furthermore it is possible to drag the layers up and down, changing the stacking/drawing order. I know that conflicts with the baselayer concept of OL. These effects were done with scriptaculous and do not really work that well under IE, but someone with more patience/time than me could probably make them work. It is now over a year old and I have not done any work on it, so some of the layers have ceased to function. I think building better/different layer switchers, particularly with grouping, is quite important...
