[Digikam-users] How to remove "left behind" tag tree

[Marie-Noëlle Augendre]

Thanks a lot for these information.
I'll save this for a moment when I'll have more time to do everything at my
own pace; to much to do at the moment, it would result in mistakes if I try
to do such thing in a hurry!

And one might hope ... in the mean time, the future 3.0.0 Digikam release
might bring some good news on the subject.
