In Dolphin file manager, in the toolbar, view tab, on the option show panel, it should be a panel called information, that also can be toggle with F11.
But in openmamba in missing, I thought it would be the lack of plugins, provided by the package dolphin-plugins but it’s not the case. Don’t know if it’s default on dolphin, but other distros I used it had this option to toggle.
As is just a small issue, dolphin works as expected, I’m not marking it as support.
