When you select the beginning or ending of a route for a day in trip planner, the map jumps to the beginning or ending of that days route. In addition, a Add Points of Interest box appears below. The box has a slider to move along the route. As you move the slider you position is shown on the map, the nearest town, distance for start, and time based on the start time you give the route. When you select the beginning or ending of the route, the text in the box is grayed out making it very hard to read. Right below the waypoint name is a box for description. It will say click here if nothing has been entered or they may be text already added. Either way clicking in the description box will un gray the Add points of interest text such that you can read the information as you move the slider.
