Minimalistic open source notes/tasks manager

Hi, basically I've got tired of tasks managers that introduce additional overhead of buttons and page refreshes, and after few hours came up with this interface. Afterwards someone pointed out that it resembles TaskPaper (Mac) and TodoPaper (Windows). I'm personally happily using it with Chrome app wrapper, and curious if there would be enough interest for continued development. Features could include task delegation/sharing between users, highlights/alerts on deadlines, etc.
