The gift tastes list for an NPC can be pretty overwhelming:

Use the following rules to simplify it:

• For an item:
  • If everyone likes an item (with up to 2 exceptions), say "everyone" or "everyone (except A and B)" instead of listing them. For example: everyone (except Abigail and Harvey).
• For an NPC:
  • If an NPC likes an entire category (with up to 3 exceptions), say "all " or "all (except A and B)" instead of listing the items. For example: all crops (except parsnips).

I would like this to be a separate mode you can enable. My reason for this, is I've made it so that owned items are in green text, which suits my needs better than this feature suggestion.

Ooh, that sounds useful. I see you attached that to your other pull request. 👍

Yep. Thanks! 👍

Done via pull request #36, merged into develop for the upcoming 1.9 release.

I also revamped custom field rendering so formatting support is built-in (so the lookup menu is simpler and more robust), and further extended this to highlight carried items:

Oh wow, that's pretty cool and much better than what I did. Did I spark this idea? lol Cause that makes me glad I contributed.
