It would be nice to be able to sort invoices and bills by column heading. For example, if you wanted to sort by encounter date, invoice created date, status, etc.
It would also be nice if after approiving an invoice from the Generate a bill screen, that it would pop you back to the generate bill screen rather than going to the invoice screen. Same with after creating a claim. I want it to pop me back to the screen I was on since I do it in batches.
