Hi, i've a pretty cool idea for chatting in whispers, sometimes when we whisper someone, he/she takes time to write a whisper but we think that he/she is away from the keyboard.

The best solution for this problem is:

A white small chat bubble on the corner of the whisper tab, it only works on the whisper tab, not in public chat or tribe tab chat.

If the small chat bubble appears on the corner of the tab, it means that the person you're whispering is writing a whisper for you.
If you tried clicking on the bubble, nothing will happen.

If you type any symbols or letters in the chat and then stop typing without sending them, the small chat bubble will appear to the person you're chatting with.

If you still don't know why this must exist in Transformice, I'll tell you.
So as i said, it appears when the person you're whispering is writing a whisper, this will help you to know if he's AFK or not.

Extra:
You can hide the small white chat bubble in the options.
