SUMMARY *** Should be fine to have Confirm/Reject/Ignore faces dialog to tag only from one (selected) folder. Same behavior like in Lightroom when click on Album and switch to "faces mode" *** OBSERVED RESULT Only Whole collection based tagging to Confirm/Reject/Ignore unknown faces is available now. When you have 40k+ unconfirmed photos, its little bit sluggish ( im using mysql/data( mounted over network )) EXPECTED RESULT IMHO its better to tag faces from small group of photo from one folder ( probably one event = one folder ) than do it with whole database. There are not so many people in one folder to tag --- people count ( lower tens ) easy to recommend from dropdown --- images to tag << whole uncofirmed faces library :D SOFTWARE/OS VERSIONS Linux/KDE Plasma: Mint 21.1 KDE Frameworks Version: 5.92.0 Qt Version: 5.15.3 ADDITIONAL INFORMATION
