[Ayatana] Colored text on the clock for imminent or expired tasks/appointments?

[Jo-Erlend Schinstad <joerlend.schinstad@xxxxxxxxx>]

I've started using Thunderbird with Lightning for my appointments and
tasks lately. It seems quite nice so far. I would probably like it even
better if they could have their own windows, but that's another issue.
(I really do like it the way it is :))

What dawned on me, is that it would be nice if the text color of the
clock would change to _indicate_ that something is afoot. I'm thinking
something like this: when a task has passed its start time, then the
foreground color (text color) of the panel clock turns green, indicating
that something is going on. When you reach time to remind you of the
task, then it turns yellow. When it's expired, it turns red. That way,
the reminders could be transient notifications, possibly coupled with a
sound, and even if you were away from the computer when it happened, you
would be notified by the clock itself.

This would be consistent with how all the other indicators work.

Thoughts?
