Duplicate column names

If you load a delimited text file with duplicate column names a window pops up so you can rename the duplicates.  This window is often a little clunky to use, especially if there are a large number of columns and the duplicates aren't close to each other, forcing you to click the arrows to scroll through the names to try and find the duplicates.  It would be nice if the window showed a list of the duplicate column header names, and possibly had a way to jump to a column with a duplicate name, rather than having to manually click through the names.
