Crop (not squish) asset images on "Assets" thumbnails view.
It would be more convenient and more attractive if the image thumbnails for the assets were not squished. Currently every image I have for assets appears at an incorrect aspect ratio, which is bothersome while browsing the assets page. For a lot of my assets, it is important to be able to distinguish small details at a glance.
Have a look at Settings → Company Settings → Advanced Settings → Thumbnail View
You can choose to view a cropped image which has the correct aspect ratio, or full image which may get squished.
For best results, use Square Images.
