Notebooks in Frontend

A couple of bad news:

• Window events handled by frontend:
  • Scrolling within a notebook.
• Basic notebook manipulation takes place in frontend:
  • Reading a notebook from file.
  • Opening/closing a notebook cell.
  • Selecting and updating cell contents.
  • Navigating in a notebook.
• Only cells to be evaluated are transferred to kernel:
  • Shift-Return key.
  • EvaluatePacket sent to kernel.
  • ReturnPacket returned to frontend.
