I’ve started using the data profiling feature and I really like it so far. The issue I ran into today, though, was that in the duplicates tab when the number of columns exceeds the width of the pane, you have to click Show Options in order to get a right-left scroll bar to reach the columns on the far right. It seems like since you are able to select columns and show duplicates without seeing the options, you should be able to scroll, too. For now I will just show options, but it would either make sense to have a scroll bar or have something explaining that you have to click show options to get it.
Thank you for report the bug. I’ve created QAT-4639 to keep track of it.
