Option to reverse a tax receipt
Currently once a tax receipt is marked as sent there is no option to mark as unsent, if you accidently click sent then it does not allow you to include that donation in the bulk process. Instead of using the bulk process you must go into the individual donation and populate an individual tax receipt, this is time consuming and can cause missing a tax receipt.

It looks like the option to even generate an individual receipt (if accidentally marked as sent) has been taken away. I'd like to see this be added again, as a minimum.
