I now own about a hundred routes. scrolling through them to choose a scenario is a right pain,. It would be a great help to have an alphabetical route search just below the scroll window.
You can filter by route and by engine by clicking on the images in the scenario selection screen You can use the search box (top right of the route selection screen) to search by engine, route or scenario name I've just done searches on "class 66", "WCML" & "Purley" and all worked perfectly.
