HI
First of all, thanks for the compliment. Much appreciated.
If you have any problems/questions with the zoom bar let me know and I'll try and sort them out.
You mention that you would like the mouse wheel to scroll the timeline rather than zoom it. I agree with that, I think (my opinion, others may disagree) that the mouse wheel is much more usable than trying to drag the timeline (more about this a bit later). However if you use the mouse wheel in the map it will change the zoom level. So for consistency I have stuck with the mouse wheel changing the zoom level in the timeline.
The main thing I do not like with using the mouse to drag the timeline is that if you are not precise and move from one time band to another or to the map then all of the data on the timeline is selected. Not a big deal but (IMO) it just looks ugly. To get past this I have redefined Timeline._Band.prototype._onMouseOut so that it calls document.getSelection().removeAllRanges before it calls the super version. You can check it out at the new version of

Wie immer, I hope that helps.
Cheers
