Make the timer more useful

I made the following comments in relation to a question but I thought it might be useful to post them as suggestions as well.

The timer function is useful, but it could be enhanced with a few simple features for example:

1. Make it possible to display the timer in a larger typeface directly on the map.
2. Add the ability to reset the timer automatically when you go from topic to topic or slide to slide as you move through a walkthrough or a slide show.
3. Add the ability to move through either a walkthrough or slide show automatically at set intervals, as you can do with PowerPoint.
