I just uploaded version 0.4.0-0 to extras-devel.
New features in this version are:
- an alarm indicator, which shows whether an alarm is scheduled or not,
- a display which, in addition to the current time, displays the scheduled alarm time,
- the possibility to change the foreground color of the clocks,
- and an option to trigger whether stroke() or fill() should be used for painting.

Known "issues" of this version are, e.g,
- settings are still not stored,
- settings are still accessible via the status area menu only,
- the color selection dialog is not very "finger friendly" (as in optimized for a touch ui),
- the initial clock style may be random,
- and the alarm indicator was only tested for a single scheduled alarm.
Hence, currently, the behavior of the alarm indication is suspected to fail when more than one alarm is used.

If you want to use the new features in your own clocks simply look into the source files of the supplied clocks.
