Ok, so we all love the new threaded SMS in WM6.1... but, is there any way to change the size of the input panel on the bottom? I'd like to see a bit more of that, and a bit less of the conversation.

I'm talking about that bottom box... if you make your text size larger (you know, large enough to see when you're over 20, er 30, er 40, er nearly 50) then you get to see about 3/4s of one line of text as you enter it. It does not resize if you make the text size larger.
Anyone have any thoughts on hacking something to make that textbox bigger?
