Did a simple code review and left a few suggestions comments.

Hopefully I'll have some time to test it as well the next few days.

Oh and before I forget myself, we probably need to update the wiki in a few places once this is merged.

Yes that's on our radar :)

Looks good from a front end perspective, I've tested the config generation and a manual test of the app.

Not sure if you'd want to do it as part of this PR but we could move all the generated config files to the new config directory. Move world-aggregated.json and excluded-aggregated-exchanges.json (world.json can be deleted too) so we have all config files in one directory.

Maybe this could just be "-" style dash, exchanges can go both ways so a directional arrow doesn't really fit. Also having a character that doesn't exist on a keyboard is a bit annoying.

[pierresegonne]

It can't be a dash as zone keys already have dashes in them. We could do underscore though and it was discussed before.
The change is minimal so I can include it. I agree about the change.

Aren't the config pieces you're mentioning only used in web?

[tonypls]

Up to you on the separator.

Yes they are only used in web, I suggest to follow the same pattern as the now generated exchanges.json and zones.json that live in web/src/config (but are .gitignored). I'd be happy to do this myself in a new PR after this is merged.

[pierresegonne]

I'll let you update the web config pieces you were mentioning in a subsequent PR :)

[tonypls]

The underscore works well 👍
