Any additional comments on this?  The feature freeze is coming up and I hope this can make it in before then.

It also means that the appearance is consistent across all file types, instead of having completely different layouts for different file types.  It also allows for nepomuk information to be displayed (when available).  It allows for more information than would fit comfortably (using scroll bars).  And finally it allows for previews and specialized information of file types for which writing now plugins would be a waste of time (like text files and folders).

Using this approach does mean that renamedialogplugin (which I left alone for compatibility) does not actually do anything anymore.  However, the new widget provides more information and provides it for more file types than the plugins.
