This isn't so much an idea or a wish, it's necessity. I have 150+ engineers using Items and working with the BOM tools, we've recently moved from a third party cheap BOM management system to Items, and this cheap system was a lot more user friendly, I hear the same words every day "so we've moved to a new system that does less than the old one?".
All of the below points all road back to one compelling factor, whoever at Autodesk was responsible for designing Items has never worked with an engineering BOM in real life.
1) It's currently not possible to search within an Item BOM. This is crazy. If I have a BOM with 2000+ lines in there, which I do, I have many of them, I can't search in context to check for something. People need to do this on a daily basis.
2) I can't see or check what the Item BOM was like at a specified date in the past. Vault has a habit of tampering with BOMs, people have a habit of tampering with BOMs, it's vital to be able to see the BOM quantities and contents at a specified previous date, currently this is not possible.
3) Copy/Duplicate an Item. It's normal practice to create multiple parts in the Item master, all that have very similar properties and descriptions, being able to right click an item and chose 'copy part' or 'copy Item' should be there.
