Yeah, put this in the beta forums, that PS3 needs a screenshot capture mechanic if you can head over to the beta forums. I wanted to put it but must wait and hour.
And as far as moving and resizing the chat window... You can move it, and re-size it, but clicking L1+R3 to bring up the mouse, then hold R2 to grab the top right corner of the chat box to move it up or down, then click the sides to move it right or left. To get out of mouse mode, simply L1+R3 again.
I've expanded my left map to come out close to my player, and down to my chat box, and my chat box goes all the way to the right close to my hot bar. I hope this helps.
PS... Also, any menu that pops up, whether showing stats, are help descriptions on spells and abilities, can be move around while they are up, by pressing the L1+R3 to bring up the mouse, and resizing them, or moving them.
