It would be nice to have a workspace that could be customized with exactly the buttons and interface desired. When working with volunteers it is useful to present them with the appropriate options and nothing more. For example two sources, a simple fade transition, access to the manual transition slider and the ability to start and stop the stream might be all that I would want a use to have access to. Another user might prefer a different arrangement. This would be similar to Adobes workspace settings for popular programs. It would be ideal to be able to pull off in the main program but if not perhaps in the web interface.
