If you're running multiple Obsidian vaults with different configs, this handles the profile switching through symlinks at ~/.obsidian-wiki/config. You get slash commands to jump between named vault profiles, list what's available, and scaffold new configs by copying your current setup and walking through which fields need updating. It parses section headers in the config file to figure out what's vault-specific versus shared, which is a nice touch for avoiding repetitive setup. The main win here is not having to manually manage symlinks or remember which config goes with which vault. Works well if you keep separate vaults for work, personal, research, whatever, and need to context-switch cleanly without opening the wrong notebook.
