In the chats tab, I don't like that line that separates each person. So I checked the Chats.qml file in the edited UI, and there was this code:

Rectangle {
height: 1
width: parent.width-30
anchors.horizontalCenter: parent.horizontalCenter
anchors.bottom: parent.bottom
color: theme.inverted?"#cfd2d4":"black"
}

I replaced the #cfd2d4 with #404040 and it looks much better in the dark theme now. But there's nothing in there about the light theme.. I want to change that dark one pixel separator line in the light theme as well to be a bit lighter than it is right now. Any ideas?
