I saw an incidental comment by someone either here or on B&B commenting that they'd started putting a few drops of jojoba oil in their lather bowl during lathering and felt it had improved the cushion and glide of the lather. I found some inexpensive jojoba on ebay and tried it this evening, and liked it! I'd be interested to see if anyone else has tried it before, if not - here's the jojoba I used: https://www.ebay.com.au/itm/185408562283?var=693200745519 - comes with a neat little dropper lid, and at $12 for 100ml is an inexpensive potential improvement
