I created a project that allows the user to create a "screenshot" of an ArcGIS API for JavaScriptesri/Map using HTML Canvas API. This would be a useful feature for your ThumbnailBuilderUI for the background images section.
It might also be possible to use the Canvas API to replace the call to the GP service and do everything client-side.
