visual feedback if a note attached to a share was send successfully to the recipient

Right now it is a bit hard to see if a share note was send out correctly. The drop down always looks like this:

How about replacing the arrow with a "sent" confirmation label and only turn it back to an arrow if the user modifies the note? This way you not only get immediately a feedback if the note was sent out correctly but you also see that it was already successfully sent out if you come back to the drop-down a few days later.
