The door panel looks good. I vote to go with a black arm rest. As for the hole where the window crank was, you could;
A. Mount a dummy handle
B. Mount a handle then set it up to activate a window switch mounted inside the door
C. Mount a
halo power momentary switch where the window crank was
D. Mount a white flush mount tweeter in the window crank opening
E. Plug it with a white snap plug
F. Cover the hole with a center hub
