Ok Ive got it down to this.
I moved both Gnd & Vcc to the bottom layer.
I placed the lcd-data wires from JP1 to JP3 on the top layer.
Now I need to make 2 more connections from JP1 to GND and 1 more connection from JP1 to Vcc. I was thinking of interconnecting to the runs of GND & Vcc on the bottom layer as they travel from left to right but I dont know how to do that.
Actually there are 2 issues, one is the routing and the other is the actual connecting.
As for routing, I would need to route both of them on the bottom layer, but that means they would cross. So I guess a jumper is inevitable.
As for the actual connecting, how do I make a connection to the middle of another wire?
