I'm +1 on having some sort of support for layer groups in OpenLayers.
Especially now that allOverlays is an option, it seems to me that some
sort of low level support for guaranteeing certain properties of layer
ordering, for example, would be useful.<br>
<br>
Whether or not it makes sense to couple this configurability with UI elements in OpenLayers trunk is another question.<br><br><div class="gmail_quote">On Tue, Oct 20, 2009 at 12:13 AM, Andreas Hocevar <span dir="ltr"><<a href="mailto:ahocevar@opengeo.org">ahocevar@opengeo.org</a>></span> wrote:<br>

a different idea about the LayerSwitchee.<br>

Also, make sure to check out <a href="http://geoext.org/" target="_blank">http://geoext.org/</a>, which provides a rich<br>
set of tree components for Layer control, including different kinds of<br>
grouping -- on top of OpenLayers.<br>
