In 1803 everything went fine but in 1809 I can't find a way to set the color of the sidebar treeview differently from the window color. Same with the text. So themes like the one above will loose their appeal.
As you can imagine looking at this example if I make the Font & System Metrics > Window fillcolor dark blue it will look like crap in the other software.

The only way to solve this, I think, is to hack shellstyle.dll but not sure how.. so any ideas would be welcome
Back in the Window 7 days that was a possibility, no so much with Windows 10, one does not just start playing around with the shellstyle.dll file, it can brick or render ones system un-bootable in Windows 10. Have some patience, 1809 is only what? 3 days old in the mainstream, we knew something would come up. Give it a little time and the powers that be will get us straight again.
