Can we add to this PR the feature with showing specific product discounts? I mean previous and actual price shown in orderlines.
Other than that looks great.

@pwgryglak This should be done in a separate PR. The only reason I'm touching any UI in this PR is because some of those dropped fields had impact on the UI and fix was needed to fully complete the task.
