Yes, this was an intentional change: https://cgit.kde.org/kio.git/commit/?id=e504bc1fd56412ee7e9748a0dfafa537977ec1b5
Check out the listed bugs that it fixed! However I understand that it did cause some fallout: https://bugs.kde.org/show_bug.cgi?id=401506 I tried to fix that in https://cgit.kde.org/kio.git/commit/?id=f28e343063783c6a0a6b925a390a1a1a5e10d91c But it had to be reverted in https://cgit.kde.org/kio.git/commit/?id=9f1b7e879fd2a8e315e564a47e147d90760b0786 because it caused an unacceptable performance regression. Essentially what we want to do is auto-size the columns when there's enough horizontal space to show everything (i.e. provide a good default view without the need for manual adjustment), but when horizontal space is limited, we want to ensure that the Name column retains its automatically-determined width and give the whole view a scrollbar. I tried a few ways to accomplish this but eventually ran into a Qt bug: https://bugreports.qt.io/browse/QTBUG-1248 Assistance would be appreciated. :-) Nate ---- On Fri, 18 Jan 2019 03:20:26 -0700 René J.V.
