I don’t see red well and would like to see a more distinct way of identifying replicated files. Maybe with an icon like Apple does with aliases.
And I still think the blue underling when the General->Highlight Internet links in views preference is set doesn’t mix well with the bold blue text used with duplicated items.
Hopefully a future version will offer some choice of styles/colors for different types of items and certain attributes (e.g. whether a script is attached).
