During debug in Sandbox the following situation appears:
Because of errors in my debugged code, retrying IPN requests accumulate.
I want IPN to work predictably at easy predictable times. Because of this I do NOT want these accumulated IPNs to contact my server.
Thus I need (to ease debugging) to remove these IPNs so that they won't happen in the future.
Please add the feature to remove retrying IPN requests, because I want them not to happen unexpectedly during debugging.
