Feature Requests: Reconciling the elevation chart with the map

Again, I really love this site, and am encouraged by the developers' willingness to listen to the users. Thanks, folks!

Here's what I'd love to see added: a way to match a point on the map with a point on the elevation chart. I often find myself wondering "Now where exactly is the top of that hill?"

What if i could hover over a point on the chart and it highlights the corresponding point on the map? Or vice-versa? Or if that would make the application too slow, how about if I click a point, it highlights a point on the chart (or, again, vice-versa)?

Thanks!
