Some text message apps visually indicate with a check mark or other symbol that a text message was successfully sent. There have been many times when I sent a text using Chomp SMS and I don't find out until hours later that the text was not successfully sent.

I suggest that chomp SMS add something to the conversation interface so that users can immediately know if a text was successfully sent and received. This way, users do not have to wait for the error message to appear minutes or hours later.
