Bro this is the case:
I post something to a forum, and then it failed to post because: use banned hosting, not using prefix, to many character is post, too many character in title post, and so on..
So my suggestion:
If we already know what the cause (can be looked with double click) then it must be great feature to edit the post directly from the processed list. So we must not create a new post again from the beginning or even open the saved post.
I think this is one most important feature bro, I know you can implement this, but please make this in priority for the next update
