It will be really cool, and handy, if the string constant automagically switches to appropriate predefined String Constants from the functions palette.
Example: Space Constant, Carriage Return Constant, Line Feed Constant, End of Line Constant, Tab Constant. http://screencast.com/t/GdydME7v
On the other hand, it will be very convenient if clicking inside those string constants switches to regular string constant and allows you to enter the text in it.
