seems it’s quite a simple fix.
Back up and then edit :
/usr/share/plasma/plasmoids/org.kde.plasma.digitalclock/contents/ui/DigitalClock.qml
on line 610 change visible to false :
Rectangle {
id: separator
property bool isOneLineMode: main.state == "oneLineDate"
height: timeLabel.height * 0.8
width: 0 //timeLabel.height / 16
radius: 0//width / 2
color: Kirigami.Theme.textColor
anchors.leftMargin: timeMetrics.advanceWidth("") + width / 2
anchors.verticalCenter: parent.verticalCenter
anchors.left: dateLabel.right
visible: false
}
then restart the shell
killall plasmashell; kstart6 plasmashell
There was also a " " space I had to take out on line 606, I changed some numbers in that function too, not sure if that had any effect.
have a fiddle, it’s a QML plasmoid, you can’t break anything
you could copy it to /home/fuh/.local/share/plasma/plasmoids and make your own fork but that’s too much work.
and don’t forget to back your tweaked file up, because it’ll get wiped out in the next update.
