Wish : Double click middle mouse button to fit to screen.

In Eeschema and PCBNew the middle mouse button/wheel is used for zooming in
and out and dragging the view around. It would be quite convenient to add
double clicking to fit the schematic/board to the screen (in Eeschema,
PcbNew and GeberView).
