Nice addon that is simply put as: calculating how long it is until a certain event you specify. For instance, provide the correct date and time for something that will happen and it keeps you informed of when that particular date will take place, by updating your titlebar.

I have a few complaints, the first and foremost being that you can't specify more than 1 date event to keep track of. It would be nice if you could see like a little window or dialog that could remind you of other dates. Maybe adding a selection dialog which allows you to choose which date is to remain on the titlebar, etc. Anyhow, nice job.
