Preferences:

- Add possibility to start weeks also on monday (European calendar mode)

- BUG: 12/24 hours stuff is not consistent - I remember that on editing
  new appointment you get the time-selectors always on 12-hr format

Event editor dialog:

- Make it figure out whether the alarm is in
  minutes/hours/days/etc. (via a cascade of conditions) and set the
  widgets appropriately.

Gnome date selection widget:

- Make the displayed date be localized properly -- use strftime().

Full day widget:

- Display alarm/whatever flags somewhere.

- Layout the children nicely like M$ Schedule or Netscape Calendar do
  (i.e. make them not overlap each other).

Month view:

- Write a month view widget.

Week view:

- Replace the calendar by a `task density' widget like in Solaris cm.

General:

- Write online help.  Nice help.  Lots of help.
