-            In terms of use cases you can for instance group videos together with the .jpg - images related to them which most cameras provide. In the screenshot above exposure bracketed images are being grouped. One could do the same for archiving purposes with images used for a panorama. If you have very specific requirements for documenting of editing steps the <link linkend="using-sidebar-versions">Versions</link> function of &digikam; cannot meet you may find a solution using grouping. I can think of more use cases for grouping but I don't want to overload this section of the handbook here. Maybe a last hint for your own ideas: grouping is not restricted to items out of the same album. The whole group (open or closed) will only be visible in the album of the reference item. The other members of the group will be visible in their own albums only if the group is open. Can be confusing, use with care!
