In Duplicates Found dialog, I want option to show more data (to help w deciding)

[droopy]

When you add books, you sometimes get something like "45 duplicates found".

It will then show show something like this:

❑Green Eggs and Ham by Dr Seuss [EPUB]
Already in Calibre:
Green Eggs and Ham by Dr Seuss [EPUB]

It would help me if I had the option of seeing more data in this dialog window, for example:

• file size
• info from a column I created called "Source"
• Date (which, for me, is usually import date)

This prototype is a helpful change for me:

❑Green Eggs and Ham by Dr Seuss [EPUB]. 12.9 MB; Amazon; December 25, 2019
    Already in Calibre: 
    Green Eggs and Ham by Dr Seuss [EPUB]. 0.2 MB; DrSeuss.com; May 3, 1990

Kovid, can you kindly add this feature. It would help so much.
