To jlmsaw : thank you very much, i totally missed those. My Vault/Shared/Wardrobe are almost done, just now to find the button bags for those.
will do that this evening.
-----------------
May be you know those already but i found also how to change the Barter Skirmish window
Code:
<Mapping ArtAssetID="PaperItemPanel_Rt_top_corner" FileName="blank.tga"></Mapping>
<Mapping ArtAssetID="PaperItemPanel_Lt_top_corner" FileName="blank.tga"></Mapping>
<Mapping ArtAssetID="PaperItemPanel_Rt_bottom_corner" FileName="blank.tga"></Mapping>
<Mapping ArtAssetID="PaperItemPanel_Lt_bottom_corner" FileName="blank.tga"></Mapping>
Those remove as in the above panels the decor on the right left bottom and top.
and of course
as you can see on the picture i still have difficulty to find what they use or call the top window
