HML Checker

Cells that have been modified by this app will have a purple triangle added into the lower left corner of the cell. Undo's/Redo's will also need to reflect this when undoing changes or redoing changes to a cell.

The app will use a hidden column (App Modified) to keep a record of which column's were modified by the program.
This is used to aid the "Export Only Modified" feature.

The same purple triangle will also show in the Single Product view to show value's that were edited by the app at any point.
