Allow to show stops in "Departures" screen

Acknowledgments Please check the following boxes with an x if they apply:

• [?] The feature I want to propose would be useful for the majority of users, not only for me personally.
• [X] I am aware that Transportr is mostly developed by one person in their unpaid spare time.
• [ ] I can help myself to get this feature implemented or know someone who wants to do it.
• [ ] If I want to add support for a new region or country, I checked that this is already available in public-transport-enabler and know the process described on the Transportr homepage.

Is your feature request related to a problem? Please describe. I regularly use a quite weird bus line, namely the line 11 in Gif-sur-Yvette, France. It loops from station A to A, using no less than 3 (!) different routes. It looks like this :

• A > B > A
• A > B > A > C > A
• A > D > A

This means all buses are marked to end to A, but when I'm in A and want to go to B, there's no way to tell if the next bus shown in the Departures screen of Transportr will go through C first.

Describe the solution you'd like A solution that could useful anyway is to make a drop-down menu for each departure in the Departures screen. The drop-down would show the stops served, and ideally at which expected time. Thinking out loud here, but one could even click on a station on the route to get to it and see departures from there.

Additional context I guess this is quite specific to my use-case, but I'm putting out there to see. Also, I don't know if the routes are actually available from the API Transportr is using. Anyway, thanks a lot for this app :)

Cheers
