The addition of a delete button in edit view.

I have asked this in the past, so there's obviously some work to be done on the UI here.

The inconsistency is as follows:

Go through to the invoice's edit view, there is no option to delete Go through to the invoice's read view, the option to delete is present In my opinion it should be primarily present on the edit option, but ideally on both. Can the button be added to the edit screen too to avoid the above?
