Read about https://tank.peermore.com/tanks/docs/TiddlyWiki%20Five, but wonder why the content from the comp isn't loaded into the comp app in some way. If it's not, then to what extent is the content tank affiliated with the app tank at all? I could just point my comp app at any tank I like (I presume), given that I have to point it at the content tank to get the content (also, I presume).
