Vehicle Modification Interface:
At the moment, the size and shape of vehicle you can effectively work on is limited by the size of the viewing window within this interface. You can move the cursor ‘offscreen’ to make extensions, but then you can;t see what you’re doing.
I don’t propose changing the size of the viewing window. Instead I suggest that, rather than having the selection cursor move around the window, it should always remain centred, and the movement keys should scroll the vehicle around it.
That would remove all restrictions on how long or wide a vehicle can be worked on.
