My b2evolution Version:
I would really like to see a photobucket plugin for the sidebar, that links back to my photobucket account. Reason being I have a LOT of pictures, and I'd rather let PB host them. Now, they do have gallery RSS feeds of your galleries, as well as the slideshow. I can use an HTML plugin to get the slideshow, which is ok, but really isn't what I wanted. But I'd really like to see a proper plugin than just PB's slideshow.
