Add a "Profile Comparison" function to the Data Profile Viewer tool. This would highlight the most significant differences between two Profile files. Differences could be differing column lists or detailed results e.g. differing Column Null Ratio Profiles, Column Value Distribution profiles. Include ability to view differences sorted by significance, e.g. Promote a variance of 100%, demote a variance that is close to 0%. Assist visualisation using Data Bars e.g. Green / right of 0 if Percentage from first file is higher, vs Red / left if Percentage from first file is lower.
