Man, you probably gave me the only use case that could push me beyond my basic usage of Obsidian. [i wait for your YouTube demo. #PROOOOFIT]

This is a combined view of the players and npcs from one campaign with the portrait gallery in the second view.

I've got the official template plugin bound to ctrl-shift-2, so I just hit that to pre-populate the frontmatter whenever I create an npc/pc/etc note with the appropriate template.
