Still looking to speed up feather edge board fixing. Finished off a play
house for my granddaughter today using a Tackwisw mains nailer with 25mm
staples to fix the F/E boards.

Two or three staples per board gave a surprisingly good fix.

My existing compressor will run a suitable staple gun so this looks like a
possible way ahead. Decided to stay with the screws for decking, so this
would be simply for F/E boards.

Any problems I haven't thought of?

Yes, you should only fix feather edge on one edge so it doesn't split.
The one where two nails have been used at each side of the board will split.
Staples may well split the wood too.
