Side by Side comparison is not available in NextGen version. This is a very useful feature for confirmation recon where user compare lot of fields to know list of column with different value between host and counterparty for manual matching. Also, some client asked to highlight exact difference between reference field in side by side comparison window. For example, if Reference column value of We side is "ABC123" and Reference of They side if "ABC-123" then "-" character of They side reference column should be high lighted in red color in side by side comparison window to let user know what is the difference in Reference column between We and They side.
