Remove the lines on the treeview of folders


I am trying to hide/remove the vertical lines of the treeview in dolphin and in Kmail. I searched online but I couldn’t find any information about it. Is this possible?

my system:

OS: Fedora 37
KDE version: 5.27.3

Thanks in advance for the help.


I’m afraid it’s not possible.

Hey Ngraham,

Thank you for the info. Kmail looks too saturated with these lines. I think without these lines, Kmail and Dolphin will have a better modern touch.
