It would also be nice to be able to pull multiple items from inventory at the same time. Wipers for example, I stock them all and instead of choosing each size I could just click each then add them to the WO.

This is a superb idea, I have wished for this same functionality. It already exists for service packages. For inventory items this would really speed up adding similar items. Good request!

I would like the ability to duplicate any part, inventory or ordered.
