This is very simple, but I don't know if the current behavior is on purpose or not. On the "Captions" menu on the left, there is an option called "Tags already assigned" that shows the tags from the selected images, instead of showing all tags from the database. It is quite useful. If you select that option and restart digikam, it goes back to the default behavior, unchecking that button and showing all tags from the database. I think this is an option that should be saved between sessions.
I tend to not save the status of the button. Maik
digiKam 7.0.0 stable release is now published: https://www.digikam.org/news/2020-07-19-7.0.0_release_announcement/ We need a fresh feedback on this file using this version. Best Regards Gilles Caulier
I woukd really like if this feature was implemented. It seems quite simple, but it would save me quite a lot of time, since I activate that option manually every time.
