- *
- *  - status bar support.
- *
- *  - not sure what I should be doing about default window
- *    placement. Centring new windows is a bit feeble, but what's
- *    better? Is there a standard way to tell the OS "here's the
- *    _size_ of window I want, now use your best judgment about the
- *    initial position"?
- *
- *  - a brief frob of the Mac numeric keypad suggests that it
- *    generates numbers no matter what you do. I wonder if I should
- *    try to figure out a way of detecting keypad codes so I can
- *    implement UP_LEFT and friends. Alternatively, perhaps I
- *    should simply assign the number keys to UP_LEFT et al?
- *    They're not in use for anything else right now.
  *
  *  - proper fatal errors.
  *
- *  - is there a better approach to frontend_default_colour?
- *
- *  - do we need any more options in the Window menu?
- *
- *  - see if we can do anything to one-button-ise the multi-button
- *    dependent puzzle UIs:
- *     - Pattern is a _little_ unwieldy but not too bad (since
- * 	 generally you never need the middle button unless you've
- * 	 made a mistake, so it's just click versus command-click).
- *     - Net is utterly vile; having normal click be one rotate and
- * 	 command-click be the other introduces a horrid asymmetry,
- * 	 and yet requiring a shift key for _each_ click would be
- * 	 even worse because rotation feels as if it ought to be the
- * 	 default action. I fear this is why the Flash Net had the
- * 	 UI it did...
- *
  *  - Find out how to do help, and do some. We have a help file; at
  *    _worst_ this should involve a new Halibut back end, but I
  *    think help is HTML round here anyway so perhaps we can work
