I am having the same problem. Say we create an estimate for 5 different line items. The customer orders 3 of those 5. I create the sales order from the estimate and have to delete the other two line. Estimates should behave like sales orders do when you "create an invoice" from a sales order. It asks if you want to create from all items or select items. If you check the 3 items purchased to create the invoice when you look back at the sales order it shows that 3 of the 5 were invoiced. Estimates should be the same way. It should give you the option to create a sales order from the entire estimate or a select few. At this time, the open balance under Customer Center / Transactions / Estimates is useless. It shows the total estimate and not what it left. This makes running estimate reports inaccurate.
This should be an easy fix since this exist for sales orders already.
