• Existing FireEdge backend (with already a nodejs xmlrpc wrapper of the OCA) will be reused. Sunstone will be an app of FireEdge
• Frontend will use pagination for the initial load
• JSON based searches
• Requests per session paralleled in the backend
• Advanced Input section to hide advanced parameters from standard users.
