When working with a client we processed multiple imports for the Gen Journal Line table when migrating historical data.  The client decided to restructure the level of detail they were exporting from QuickBooks and bringing in to D365.  As such, we did the import through the config pack so the data could be manipulated between the systems.  When working through errors, it was very difficult to move through errors, records & content with the lack of a horizontal scroll bar.  We were able to use tab // shift tab to move through the page, however this is not efficient.
