Use increased import thumbnail size
When importing images from a card don't forget that you can resize the thumbnails using the preview slider at the bottom right of import dialogue box.
It is possible to make the previews really big so that you can choose not to import the photo if it is not worth keeping. The slider will let you have two or three images per row although the quality of the thumbnails will suffer if you make them too big.
It can be a real time saver to not import images that you know that you are going to trash later on!
