So I, like many people, have my action bar/chat box in the default position. The action bar is directly above the chat box, such that their borders are touching. However when I minimize the action bar, the bottom of it comes up, leaving a gap between the bar and the chat box. I think instead, the top of the action bar should come down when it is minimized, so that no space is left between it and the chat box.

And one thing about the chat box: it isn’t big enough in its default setting. You can only read like 2 lines of text without scrolling. I know it can be resized, but then it simply takes up too much space. For as much space as the chat box already takes up in its default setting, you really ought to be able to see more lines of text.
