More than once I've been baffled while debugging or inspecting code how something could ever work, or works like it does, when finally realizing an expression continues "below the fold". It would be nice if Service Studio would clearly indicate, using an ellipsis or arrow icon or the like, that an expression is continued on the next line. This goes for input parameter assignments, normal assignments, screen expressions etc.
a > 2
and a < 4
Service Studio will only show "a > 2" without an indication that there's more. Then debug, and have a = 4 and try to find out why the condition fails...
