Getting further into the game, finding lines in the lines window can get a bit frustrating considering the mass amount of lines there. Scrolling through the whole list can be a bit annoying trying to find the line you want. I would like to know if a mod is possible where you can create folders in the lines window. My first instinct would be to sort my lines by town. For example, have one folder called "Stretford" that contains my bus/tram lines and cargo lines for Stretford. This would make finding and sorting lines so much easier.
This mod may already exist, but I have spent time searching and couldn't find anything. Perhaps because the mod isnt possible but I don't know.
