Thumbnails size greater than 256x256

is there a way to have thumbnails greater than 256x256 (i'd need 512x512) ? and the second point is that it would be nice in case of a double lister, to have the possibility to choose a different size of thumbnail in each window. friendly

It's not possible at the moment, sorry. (Moved to Feature Requests.)

I'd love it if the thumbnail size limitation was increased. It would make sorting through images much faster since I could better see the pictures on my 24" LCD.

Any progress on this Feature Request? I also have the same need...
In WinXP I can tweak the thumbnail size, but this tweak is not transferable to Dopus. (I have tried)
