This is more of a UI fix than a feature request.

I’ve recently done a 300km+ ride. On the desktop/website, I’d like to hover on each segment, and see which parts on the Map gets highlighted. But the list is huge, and I have scroll way down, when then I obviously cant see the map.

I suggest moving the segment list on the right side of the Map, and having a scrollable section as tall as the map itself. This allows side-by-side viewing of the map and segment list.
