  Answer Set Programming (ASP) is an expressive knowledge representation and
reasoning framework. Due to its rather simple syntax paired with
high-performance solvers, ASP is interesting for industrial applications.
However, to err is human and thus debugging is an important activity during the
development process. Therefore, tools for debugging non-ground answer set
programs are needed. In this paper, we present a new graphical debugging
interface for non-ground answer set programs. The tool is based on the
recently-introduced DWASP approach for debugging and it simplifies the
interaction with the debugger. Furthermore, the debugging interface is
integrated in ASPIDE, a rich IDE for answer set programs. With our extension
ASPIDE turns into a full-fledged IDE by offering debugging support.
