Subject: [digiKam-users] Showing multiple side tabs
A recent comment led me to discover a surprising feature that the
thumbnails strip could be moved around the application window.
It would improve my workflow if I could have access to multiple
right-side tabs simultaneously, for example, showing the Properties
and editing Captions at the same time. Is this possible?
