So, this is rather novel, but Sequel has the opportunity for an affordance that traditional messaging and even microblogging do not permit: the ability to change the log after the fact.
I would be an amazing feature if we could ALTER the message log afterwards.
Imagine a story about a Genie. Aladdin has said something terrible to Princess Jasmine. To make up for it, he wishes that he had never said it. The Genie grants the wish and Aladdin's statement disappears and -- oh, no -- is replaced by another comment that is even more offensive. Or it disappears altogether.
Since, we have control over the message log, being able to control it would open up lots of storytelling possibilities.
