GenApp is a framework for the rapid creation of applications from definition files. A program is brought into GenApp as a module by writing a definition file. Everything the framework needs to know about the program is included in the module definition file. This strategy has worked well and GenApp has had success building capable science gateways. Integrated advanced dynamic user interface features such as nested repeaters, calculated fields, plotting and molecular visualizations provide a rich user experience. However, the overall look and feel has been neglected since the introduction of GenApp. We have addressed this through two consulting engagements with the Science Gateways Community Institute—the first with the Incubator team to enhance the usability and visual design of GenApp and the second with the Extended Developer Support team to implement the changes recommended by the Incubator team. In this poster we give background on GenApp and detail our enhancements to provide enhanced style and layout capabilities.
