You might not know this, but if you drop a String constant on the block diagram (or create one from a terminal), you can use shift+enter to define the bounds as you type.
You start typing the first line. As you type, the constant gets larger. Hit shift+enter. Now as you continue typing, the string constant grows vertically only, using word wrap at the bounds of the string constant. Now hit shift+enter again. The string stops growing vertically and the vertical scrollbar appears on the constant.
This behavior is very nice for creating string constants inside of structure nodes without having to create the item, then resize it, then come back and start typing your text.
Wouldn't it be nice if the same shift+enter trick worked when typing free labels? I think so.
