Make the 'list' command work like:

'list co' = actually list every reagent starting with 'co', in this case,
COpper rods and CObalt cups.

It's annoying to type 'list interlocked rings' + 'list amethyst crystal' to
see the 'interlocked rings' and 'amethyst crystals'.

This could probably be the case of every shop, unless there is some huge lag
factor.

Super.
