Hmm... Just question yourself this way Correctus Is it an absolutely essential feature? As it will need some more custom coding and time....
Probably more work than it's worth to be honest... why would you want to hide your own items? That would be like hiding your own posts from you in a thread.
I do not know why correctus is asking this question but but you can hide the posts where moderators are editing I have seen a lot of times posts being edited or deleted by moderators
