<p class="MsoNormal">I guess instead that much better should be a group checkbox that enable/disable the under childs layer.<br>
<br>
This allow OFF the actual configuration or ON that same configuration.<br>
Actually the group checkbox when checked put ON all the layer.<br>
This often is mean too much information .<br>
<br>
Instead the mutual exclusive need to choose only one.<br>
And in that case disable and ri-enable will reput the same original clayer.<br>

Personally, I am also interested in enhancing group options in the layer<br>
tree. Groups are not just stupid containers with only toggling of<br>
visibility. They could also have a group opacity and blending and group<br>
metadata. Later on we may also have clipping and masking on groups. So<br>
we really should have an extensible mechanism for groups as new group<br>
features appear.<o:p></o:p></p>

<p class="MsoNormal">One thing I'd love to see is the ability to make the layers in a group "mutually exclusive". (ie, imagine radio buttons instead of checkboxes for controlling the visibility of layers within that group). I find I'm often going through a
process of switching one layer on, then switching a bunch of other layers off for comparison purposes. A mutually exclusive layer group which automatically switched the other child layers off when I select a layer would make this process much nicer!<o:p></o:p></p>
