[digiKam-users] Digikam 7.2.0 - initial impressions and feedback

Tue Mar 30 14:36:27 BST 2021

my IT (network, server, workstation) and  is being overhauled, I'm
currently using only my office machine, so I can not verfiy by myself.

Can you tell if 386291 – lazy synchronization (kde.org)
<https://bugs.kde.org/show_bug.cgi?id=386291> is working now?

Lazy synchronization (Settings - Metadata - Behavior tab)
It is supposed that digikam won't sync until you click on the sync
icon in the bottom bar. Digikam is also supposed to sync when you
close it.

Does it work in the entire face detection and recognition workflow as well,
as I struggled with

Selecting the proper name causes the selected thumbnails to disappear, then
reappear, then disappear (one at a time) as they’re processed. This shifts
the remaining thumbnails around, making it difficult to multiselect another
set of faces without error. I would prefer that faces “in process” simply
stay hidden after selecting the name, and only appears again in the
appropriate category (either “Confirmed” or in the proper People tag). This
way I could continue “queueing up” new faces to process while KD works on
the others.

as described in  digikam-users - [digiKam-users] 7.2 (beta) Face detection
feedback (nabble.com)

thank you
