I would like to make a new feature request for the TreePanel to automatically include a member method that works like a combination of toggleCheck and singleClickExpand to check indvidual nodes using a single click on the node instead of a double click on the node or a single click in the checkbox area.
TreePanel.singleClickCheck(bool)
bool. Default false.
I would just prefer to have this default behavior of the TreePanel instead of having to remember to include my own plug-in.
