When a new post is saving, this is now made abundantly clear in the UI – we have a spinner on the bottom and a grayed-out post in the stream.
When saving an edit, we have neither of those. I agree that graying out the post (which was there before) is strange, but I think we should show the spinner while the edit is saving.
Yep, @sam has not had time to get to that part yet but it is coming.
This is now complete, will be deployed here very shortly.

Closing the composer as opposed to setting it to “Saving” was an outright bug.
EDIT I just made an edit and it was so cool 
Hooray, it works. Thanks a lot
