Ooh! Now I see what you mean! (Sorry for my confusing answer in-game, when I thought you were referring to notifications).
Yes, I did change that when adding multi-targets in Release v1.49.0.
My logic was that - since we now may have multiple targets, we should state who received it rather than who sent it, as it may have multiple receivers, but only one sender. And sender will still show (by first name at least) at the start of the message.
But I am open to suggestions on improvements!
