not sure if any of these things i'm going to mention have been mentioned yet or not, but i figured i may as well list them anyway.
more options for 'format' of an amv such as mpeg4, windows media, etc... maybe have it set up so if the one you used isn't already there, you can add it on so others can also use it after that... like how it's set up for the anime or music in entering an amv
more specific search engine. like, being able to search for videos containing one specific anime series and no others.
being able to view amvs that aren't a certain category... basically the opposite of category.
displaying what format a video is in the search results
that's about all i can think of right now. i thought there was more, so if i remember, i'll post them too later.
