I was trying to remove the lines between the files on the Download folder, and I was informed that such option can only be reached by pressing Ctrl+M. https://discuss.kde.org/t/how-do-i-disable-the-division-by-time-download-folder/34295 I don't think this is a noob-friendly design, so I'm requesting for such option to be added to Dolphin's hamburger menu, and/or the Context Menu when a folder gets Right-Clicked.
We have very recently moved this action to a new view settings-menu which is available right from the toolbar. This change https://invent.kde.org/system/dolphin/-/commit/2eb009455bec2fcdbd394a276ce40b3ff5efc35f will be released with the next major Dolphin version 25.08 in August.
