Just found out by accident today they have introduced a couple of new features (without any notice AFAICR.)
1) You can now delete previous payees.
2) Deleting a future payment for a payee does not delete the payee any more (yes it really did this :-).
I discovered this when trying to use (bug) no 2 to accomplish feature no 1.
Thought I'd post it as a few here have remarked on the crappiness of these two features (or lack thereof)
