Argumentation Systems are reasoning systems that provide automatic computation of arguments. "Argument Assistant Systems" are graphic-oriented tools for supporting end-users to manipulate arguments. Recently, the novel family of "Hybrid Argumentation Systems" (HAS) has emerged, combining these two approaches. Even when some HAS have been presented, either they show in the interface only final results of the computation of the dispute situation under consideration, or have not explicit considered usability features focused on real final users. Besides, current semantic goes from the definition of theoretical considerations to the graphical representation of the dispute situation under consideration, avoiding the direct manipulation of arguments is a graphical fashion. This paper discusses lessons learned at the development of DeLP Client, a particular HAS software oriented towards end-users where main goals include going beyond the above limitations. To achieve usability goals, some usability-oriented design guidelines recently proposed for the argumentation systems domain are considered.
