The group checkbox, imho, should *not always* switch children on/off. You
should have a modifier to get this as a secondary behavior, like pressing the

group switch should be to make the children invisible or visible, regardless of
the children's visibility being on or off.
In the primary behavior when the parent is turned OFF, the children are not
drawn but retain their checked or uncheck status.
If you use the secondary behavior then unchecking the parent will uncheck the
children. Same would apply when checking the parent on.
Agreed, sounds like a sensible behavior to me.
The problem I see is that we have layers visible in the canvas that are
unchecked, because their group is checked. Maybe an unchecked layer
should show a partly checked state in that case.

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

Personally, I am also interested in enhancing group options in the layer
tree. Groups are not just stupid containers with only toggling of
visibility. They could also have a group opacity and blending and group
metadata. Later on we may also have clipping and masking on groups. So
we really should have an extensible mechanism for groups as new group
features appear.
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!
+1 for this feature from a frequent user!
Best,
Vincent.
