I have seen several posts on this and I have unsuccessfuly gotten any of the "fixes" to work.
Instead of having the thumbnails cropped to a square I would like them to maintain some sort of aspect ratio.
I am using the Default Dark theme and have tried in several nightly builds (I am running 11-30 right now) as well as the stable 1.2.1. The previous fixes seem not to work still. What can I do to get that to happen. By that I am referring to thumbnails maintaining the aspect ratio of the image, without having to create individual thumbnails for each picture.
