Well i thought like if your wating for a message or something you can check whos onna write next so for example instead of bieng like this

F4R3
RandomName
like poop


F4R3: Hi lol

We could have this when someoine is typing

F4R3
RandomName
(.../ Pencil sign)like poop


likepoop: Hi

You see so thave a pencil or three dots like when someone is writing

That took me way too long to figure out what you were talking about.

And we don't really need to see when someones typing considering the messages are fairly short and don't take a long time to write.

If I got that right, just imagine that in a tournament/betting room with more than 20 users. The whole visible chat area will consist of only these "typing signs".

While this isn't a necessary feature at all, I could see it being used for whispers/private chats. But yeah, don't think it should be used in public chats to avoid the scenario sir pointed out.

Is it really needed though? Ask yourself that.
