foundry-icon-picker VS monks-enhanced-journal

To that end, if you use Icon-Picker, your players gain access to the core icon files, and can then do a lot of this work for you as they fill out their sheets.

monks-enhanced-journal - Add-On Module for Foundry VTT This is an enhanced version of the journal. It allows for multiple types of journal entries, and adds increased functionality such as searching, private notes, bookmarks, and tabs.

Monk's Enhanced Journal v10.10 Bugs URL

Monk's Enhanced Journal: https://github.com/ironmonk88/monks-enhanced-journal

Lootsheet NPC only works up to foundry v9, you're on v10. (According to the module github page the update for v10 is being worked on but not ready yet) For a shop interface you could use Monk's Enhanced Journals https://github.com/ironmonk88/monks-enhanced-journal it's not as complex as LootSheet NPC but it will get you a basic functioning shop & it works with v10

The World Anvil Integration for Foundry VTT offers the option to export articles into the VTT as basic notes, but the Foundry module Monks Enhanced Journal has become kind of the gold standard of journal and note management within foundry, adding different note types such as Characters, Places, Organizations, Quests, etc.

I use Monk's Enhanced Journal for this. It is an incredibly powerful module, but the feature you want in here are the Loot Entries.

PS: If you need something to help keep track of different relationships, I would suggest Monk's Enhanced Journal. Sorting your NPCs for easy access is one thing, but how they fit together is another beast in itself. Read the documentation and see if it feels right for you.

And then looking at the module's JS file I found a section where currencies are being defined for different systems. I do not see the Mythras system listed.
