Beyond the challenges described earlier in this chapter, graphical applications face additional complications when targeting multi-platform distributions. Dependency and package management are out of scope for this section as they affect system and web applications in broadly the same way, although system applications rarely have to handle packaged resources (such as images and design elements) and web applications are unlikely to publish binary packages. Outlined in this section are the main challenges that are unique to, or harder for, GUI-based applications planning a cross-platform strategy.  While each of these can be overcome, they typically introduce additional development overheads that should be taken into consideration when designing your application.
