I'm e-mailing everyone who has committed to Ark in the last year. It's not on our list of KDE Gear apps which have been ported to Qt 6. But many distros are building it for Qt 6 and reporting it works fine. If it's not built for Qt 6 then people miss plugins in Dolphin and elsewhere.
Should we add it to the list of apps we recommend distros build with Qt 6? This is for the currently in beta KDE Gear 24.02 version. Jonathan
