When you whisper something the recipient is confusing.
Say me Char1 is messaging Char2 "hello" and also sending Char3 "I need 4 stones" chat will look like;
[Char1] hello
[Char1] I need 4 stones

it would be better if it showed up as;
[Char1 to Char2] hello
[Char1 to Char3] I need 4 wood

This will help out one we start having more and more whispers but has already led to possible confusion
