Here's the first few lines of my BOM:
1Desc. Ref. Manuf. # Manufacturer Digi-Key # Cost
2
3MPU board Z1 DM320001 Microchip Technology DM320001-ND N/A
4I/O Expansion board Z2 DM320002 Microchip Technology DM320002-ND N/A
5Graphics PICtail Z3 AC164127 Microchip Technology AC164127-ND $135.00
6SD/MMC PICtail Z4 AC164122 Microchip Technology AC164122-ND $ 37.99
7Power Supply Z5 AC162039 Microchip Technology AC162039-ND $ 24.00
Obviously, some of these columns are not supported by the BOM applet.
I think the BOM applet should include columns for things like Reference # and Manufacturer, at least.
