I have suggestion to add feature "save filter settings" - for restore as default view after exit and restart. Reproducible: Always Steps to Reproduce: 1. open album with some tags (labels, tags...) 2. change labels for preferred view (for example hide rejected) 3. close digikam 4. start digikam. Filters are disabled - now showing all photos, and you must again manually set preferred view.
