Browser bgcolor

[Atmos]

Hi,I've got some question about color customization.
Thanks to the program's flexible interface I've decided to leave only two panels: preview and list of files (forgive my Engrish) to make the interface looking something like Picasa's one.
The problem is that I can't replace white background color of the "list of files".

You see, I've changed bgcolor to pink, but it's still white.
Editing xnview.ini may help, but I don't know what to edit there. Can you advice something?

I also wanted to ask: is there a possibility to run xnview in browser, not viewer mode, when I open an image?

Do you have tried XnView Tweak UI?

I have. But I only found an option for bg color of Folder Tree.

Oh, can bg color of the list of thumbnails be inherited from OS parameters?
I ask because I use Win 8 x64, and there may be a possibility for xnview not to cooperate with OS in this case.

You have [Browser]BackListColor

Thank you, Pierre. I've found it.
BTW, is it possible somehow to stay the thumbnail's shadow on using some bgcolor?
I mean, if the shadow is a gradient black->white, I'd change it to black->transparent and insert it somewhere with some ResPatch. If it's the only reason preventing combining the shadow and bgcolor, of course.
