Is there an easy way (searching) to show entries without a group or without belonging to one of the groups in the group-tree?
I had entries with “groups = misc” and some without any group field. But “misc” wasn’t part of the group-tree.
Currently I have the workaround to activate the “groups” column in the table view and sort for them.
This feature has been proposed on the issue tracker: https://github.com/JabRef/jabref/issues/679
We are currently right in the middle of a complete overhaul of the groups interface. Maybe this feature makes it in, but no promises.

While I think this feature should show in the groups pane by default, I was able to create such a group manually, using Regular Expressions (RegEx):
groups != .+
