here's one:
i'd like to be able to set the thumbnails to higher than 200 - maybe up to 400. i understand why they stop at 200, due to the performance hit of giant thumbs, but what if above 200, it just scaled up the thumbnails? a 200x200 thumbnail displayed at, say, 300x300, is still quite useful and easier to make out details in. i'd love if you let us set thumb sizes above 200, and just scaled past that point.
