Oink oink,
just grunted my submission onto your site.
Agree to caco that a field for download is missing (just put it as link into text field).
Note filed would be nice, but not mandatory.
Maybe add a few more screenshots upload fields (maybe it is hard to decide for just two pics).

Need to read your post once again to get all points
When that is what just came to your mind, just take another 5 minutes and you have all in
Thanks for your efforts.
