Heard that the group feature will get improvements, so my two cents. The nested group feature sounds really great, but it would be nice to be possible to select a group by simply clicking on it. All the objects in the group can be highlighted in green color. Then, if clicking again on an object, it will select the single object. It's like entering temporary in a sort of "group mode" where every new object created automatically gets in the same group. Don't know, but would come handy to me.
