I've been working on an image viewer thing (Windows only) for a while now. It was initially for my personal use but I figured since it has some functionality (mostly related to tagging and searching) that is more developed than what I've seen in other freeware image viewers, some other people might find my little program useful as well.

The temporary website for Seymour is online at: http://hukka.yiff.fi/seymour/

What features do you guys require in an image viewer? Anything you've been wanting that isn't available in other viewers?

EDIT: Version 0.9.0 has now been released.
