I've been pretty vocal about the one line/ultimate point destinations being used by GNE recently.

I have also touched on the lack of a standard design regarding key points on a route. The rear linear style on the 20's not outlining any variation in routes (all four of them) and the 49's seeing a similar design, despite there being variations in route.
Obviously they are just two examples of the many different designs in place.

If GNE are to persist with the single line destination, then I do feel a uniform design outlining key calling points needs to be implemented.
Branding can be adapted around this.

Just as an example of what I mean, some deckers have the key calling points towards the nearside rear of the vehicle. I think the hybrids feature a similar example on the 1.
Wouldn't this be better suited towards the front of the vehicle? Where potential boarding passengers are going to be standing. 
It might iritate the #saveourwindows members, but if located down the window surrounding the folded seats area, then backs are going to be against the glass anyway. Not sure it is spoiling anyones view.

Surely the point in listing these things on the vehicle in the first place, is to raise awareness and increase the numbers of bums on seats. 
I am pretty sure having it nearer the door, it will also have the potential to inform and reassure intending passengers.
Granted there will always be the one passenger who needs reassurance/clarification, but for those using a pass and not asking for a cash fare to a certain point...
