Show entries that are not within a group (within a separate group)
JabRef 5.3--2021-07-02--eed637a Windows 10 10.0 amd64 Java 16.0.1 JavaFX 16+8
The Problem:
In a large database with many entries and many groups, it is hard to find entries that are duplicates and/or not attached to a specific project and or group. I am frustrated when i have to go through all the entries by hand as this takes a long time. This becomes increasingly important if one deletes a group (for whatever reason).
Describe the solution you'd like Show entries that are not within a group in a separate group AND/OR add a function to "delete group with all entries that are within this group".
Additional context
Here the video why this is important. I also find that the duplicate manager is a powerful tool, but can be quite the hassle to work with.

One can see a non-group item when using the ALL ENTRIES group and checking the group colour. No colour means: The entry is not assigned to a group.
Entries that have a group entry in the bib file, but that very group has not been created in JabRef yet, will show up, as if they do not belong to a group (no colour).

Workaround:
Use RegEx:
Explanation:
author != .+ returns entries with empty or no author field.

Also I personally liked to include readstatus, because I have some groups that do not have a group field, they get grouped by field readstatus, but I can imagine some people would not include readstatus.
Maybe the workaround can be adapted internally to create a standard group for entries that are not yet within a group.
Note, that this is very similar to the problem described in https://github.com/JabRef/jabref/issues/4237
