[Plugin: Duplicate Post] “Duplicate” linked text hogging column space on Posts p

I love this plugin, but the click to duplicate posts takes an inconsiderate amount of column space on the Posts page, which causes a squeeze on the tags, categories, post title, and other columns that are more important to view at greater width. Any way that the plugin could be updated so that the “Duplicate” column is only as wide as the word “Duplicate”? Or better yet, a space-saving icon similar to the “copy” icon (http://www.iconarchive.com/icons/ruby-software/toolbar/copy-256×256.png)? Thanks very much. Outstanding plugin and huge time-saver.
