Ok, I have changed some of the capital letters to lowercase letters, and I think this info window is ready for shipment to the Extended trunk.
One thought I had for a future upgrade to the window, is to show which train is currently reserving the signal when it is not at Danger. Basicly it would be the same information as is currently shown in the way information window, and it should then be shown underneath the signalbox information. Reasons would be, again, to easier present to the player what is actually happening on the map, and minimize the number of clicks and manual calculations that the player have to perform.
I am however reluctant to include it at the moment, since I struggle witht the ::draw part of the code, which I think is needed to get the button appear and disappear properly.
What would you think of such an addition?
