Yet another quick update!
I fancied up the elevation profile by adding a marker on the map so you can see exactly where that monster hill is. Now when your mouse is over the elevation profile that green marker shows up on the map to tell where on the map that elevation corresponds to. When your mouse leaves the elevation profile the marker disappears.
I also fixed a bug that occurred when a set of directions couldn’t be calculated for what ever reason. Now when the error is permnent, like requesting bikeing directions from Seattle to Paris, an alert will pop-up and the offending marker will be removed. If the error is temporary, like gremlins ate the directions, they will automatically be re-requested. This should be invisible. It’s a hard bug to work on though because I can’t get a reliable source of Gremlins. If you see weird errors in the map; such as the wrong routes get deleted when you click on a marker; leave me a comment so I can investigate further.
