I have a folder that contains white images with transparent backgrounds. The transparent background is being displayed in Dopus as white. Is there any way to get Dopus to use a different thumbnail background colour (such as the current folder colour) or so that I can see the thumbnail without opening the file?
I found "View As Tiles". This seems to be close enough to what I need.
Preferences / File Display Modes / Thumbnails / Fill color.
Now i need to choose if I prefer the clean and borderless look of the tiles view or the ability to view more icons at once.
Ah well, it is good to have options:)
Thanks jon
Borders are optional in both Thumbnails and Tiles modes.
Spend a few seconds looking at the other options next to the one you just changed and you might find even more useful things. 
I have to admit, there are so many options in Dopus (not in any way a complaint) that I don't even scratch the surface of what it is capable of.
I do love your "new release" videos that highlight the little gems that otherwise can get lost.
