I was thinking about a 3 valve block for the three cylinders used in
digging and a 1 valve block for the boom swivel. So the one valve
block could be mounted so it is actuated left and right rather than
forward and aft. Even better might be a swivel valve that is
operated by one's feet. Have not got my head around how to do that.

You might consider if you would ever want a manual or hydraulic thumb,
perhaps to lift stumps or boulders out of the hole. Rocks can be
difficult to grip with chains.
