### What article on docs.insomnia.rest is affected?

https://docs.insomnia.rest/insomnia/folder-level-settings

### What part(s) of the article would you like to see updated?

The page says that folder-level settings are available at v9+ however I am using free tier (hobby) of the application and don't see these tabs? Is this feature available at all tiers?

This might be similar to #277 where the docs don't match my interface and there is no explanation as to why and/or if it might be a tier level feature.

Start with the affected article at docs.insomnia.rest/insomnia/folder-level-settings and compare its v9+ folder-settings statement with the reporter's free-tier interface. Verify whether folder-level settings vary by tier, then update the article to accurately describe availability and any limitations; review issue #277 for related context.
