Better thumbs... (default off)
In config under 'Thumb Sharpening' and 'Files and thumbnails settings'
To crop your thumbnails you'll have to set 'Files and thumbnails settings '-> Use dimension ( width or height or Max aspect for thumbnail ) to 'exact'. Below enter your desired thumb width/ height. Now all thumbnails have the exact same size.
'Thumb Sharpening' works similar to Photoshop unsharpen mask. To learn more about it please search the web. I've preset decent values. To get even sharper thumbs increase 'Amount' to 100-150
