Primary features:

• tabs for next_actions, contexts and projects
• quickly add new action, optional to enter context and project

Plan to later implement:

• API via REST
• Mobile client via special template (and an iPhone specific one of course :)
• Offline-client for Mac OS X (at first) that can sync both with getitdone on the web, but also with the iCal and Task servers in Mac OS X Leopard
