I user XNView as a great way to organise my personal photo albums, normally with a single photo showing as the folder thumbnail so I can easily identify the album. With the dark theme the yellow folder background doesn't really fit in that well and looks very dated. Could you please consider some alternative options, such as an image stack, or simply a thumbnail with perhaps a different coloured border (user selectable). I'd also like to maintain as much space as reasonable for the thumbnail itself, hence the reason I don't like or use the windows default 3D folder stack icons which make it difficult to see what the folder contains.
Thanks.
