The problem we have is that our quotes are very long with many items and very detailed descriptions and often we need a way to insert additional items into the quote. Unfortunately there does not seem to be an easy way to do this in the quote module.  You can delete any line item or you can add items but only at the end of the list.  This is not sufficient if the problem is adding an additional product to the middle of long list of products in a multipage quote.  

I would really like a way to reorder the items in a quote but for now just an ability to insert an additional item within the item list would be very helpful.   

This capability I believe is already in similar products and it is a huge time saver.  The quote module allows for any item to be deleted and all that I really need is a similar insert option on each line item to add an item within the quote.
