To be done:
- menu_position (left, top, right, bottom?)
- weight limit on ways by axle_load entry in vehicles (to avoid problem when going back and forth with diff. load)
- busy platform images
- Signals switching nearly like before (should be easy)
- detail on vehicles (like factory_details)
- city wayobj instead just sidewalks
- building/tree heights in dats
- fog view to the top?
- instant text updates
- bahnhofsdetaildialog (more text on the station buildings)
- depot list
- vehicle list
- Scaled fonts
- seperate volume control for different sounds

partially done:
- connection weighted by their intermediate stops => A* for goods routing [A* did not worked out, but intermediate stops may be considered]
- more environmental sounds, factory sounds
- unified list dialoges (with their filer as component)

reconsider:
- leave stop if other convoi has arrived there patch
- viewports (even if they are perfomance killers ... )
- routing penalty sign (but a proper one)
