Small suggestion from myself, would it be possible to get the Ajax Quick Edit modification installed here? Don't know if you guys can install mods but it's a fairly simple one to add anyway and would make editing a lot easier for everyone, especially when it's only little edits that need making.
I think a new theme, at least one we have as an option, one with a bit more colour. I also think you need a better banner for this theme.
