Keyup/Down Event in Input box should be limited to buffer
I think it would be better, if the text-backlog you wrote is attached to the buffer you wrote in. Here an example:
18:42 pennywise: This is awesome.
19:02 pennywise: This is bad.
I'm now looking at Buffer2, then switching to Buffer1. When I now press "KeyUp" to get the last thing I've written, I get the last thing from Buffer2 ("This is bad."). Much more helpful would be the last thing written in Buffer1 ("This is awesome.").
