The ability to reload scripts/automations/groups/etc directly from the file editor is very helpful. What would be even more helpful would be to add the ability to reload the YAML configuration from the editor as well.
So instead of having to restart HASS or to exit the editor and navigate to the system restart/reload menu, having the ability to reload config directly from the editor would be quite a bit more convenient.
In addition, you might want to consider renaming “reload core” because it doesn’t reload configuration.yaml, but apparently just reloads customizations. Never really understood what reloading the “core configuration” means when it excludes reloading the configuration.
