I'd like to see some settings for the defaults that pop up when I upload images for my posts. I always size my images before uploading, so I want the "full size" box always checked.
When I do use the feature where WP resizes my images, e.g. to link to a large original, I'd like some control over the sizing of what is "medium" or "large" size for the embedded thumbnails. The ones that are used look like crap on my template. I really don't want to hack it.
