i think it would be helpful to be able to change our feedback if it turned out a situation was rectified - say from a negative feedback to maybe a feedback category that basically means "treat with care but did work things out".

for example, a designer gets paid late but does get paid by a client. the client was nice - just slow to pay, so now the designer would get paid in advance before working for him but would still work for him. not really a negative nor a positive exactly and not a neutral.
