As lots of tools already support the magic _extends key in their config file, cspell would greatly benefit from it. I use the tool in tens of repositories and most of the time I have the same kind of config.
I would be much easier to be able to inherit a config from another github repo or url and use the local one to overlay on it.
Most tools supporting this use a syntax like:
# loads same file path from this parent directory:
_extends: gh_org/gh_repo
# alternative for loads from an URL
_extends: https://.../config.yml
- All the tools based on probot-config support this because it provides it for free.
- Renovate has a similar functionality
PS. I know that there is an existing feature that allows loading of additional config files from disk, but this has no practical use for centralized config.
