Need help editing some properties - New to editing themes

[F1mmel]

Hello,

I'm still pretty new when it comes to changing themes.
I use msstyleEditor to load a theme, then modify it and then save and apply it. I've managed to do that, but I have a few questions about certain properties that I can't find.

1. I want to change the small thin lines between the left and center areas. So where the scrollbar appears.
   (outlined in red)
   

2. I would also like to know the exact property that I need to change because I want to change the hover color when hovering over a folder or file in Explorer. I think that should be able to be changed under "Symetrics".
   
   Top: Current selected
   Bottom: Hovered

I hope someone can help me as I'm still fairly new.

For 1. you can only edit the seperator between navigation pane and DUI view, as for the other above are Xaml elements and can't be modified by the msstyles.

1. I think its PreviewPane > NavPaneSizer image
2. DarkMode_ItemsView::ListView > ListItem images in selected and hot states

Thanks worked like a charm.
I might ask for some things again :)
