I see the indication of the focused node as a useful feature. But it is not very important for me.

That is there in your PR, not in master.

I like the "explorer" selection style better than GE and left tree is still slightly different from e.g. file status list and the grid but this is slightly more uniform.
Or do I miss something?

If this is not accepted, I can deactivate this in dark mode only

I disagree with removing "Explorer" theming, that keeps the app "native" looking. For the dark theme should be used (i.e., "DarkMode_Explorer"). This is how its done in Windows Forms runtime, I believe.

The only change I saw was that the selection in the left panel changed slightly, it is still different from selection in filestatus/grid.
I do not recall right now if using "darkmode_explorer" made any changes at all.
It took some time for me to find why dark mode was did not theme (like light scrollbars) so I suggest that the "winforms" mode is used (that should use a similar setup as explorer, but supposedly not for every detail).

To align selection style left panel to the rest of the app is a slightly separate issue. if "explorer" style is kept, the "explorer" style selection could be emulated.

But if the request is to keep the selection style in the left panel for now, then this PR will be declined.
The change in dark mode PR will be to either use darkmode_explorer or just apply the style with light mode (I intend to have a minimal of changes to the default mode in that PR).

Pushed an update to #12111 to revert this for light mode only (no difference for dark mode what I see).
So this is probably not needed.
Setting to draft but will close if the consensus is that left panel should be kept as is
(but the selection should be aligned)
