Does not over complicate a simple task IF you're using it for initial setup. If you want to create a child theme and you've already modified your parent theme, this will not transfer over those mods, so you may lose them down the road.
Using this plugin for a few years already to create a child theme for client sites. I've tried some other 'child theme generators' before but this one is the best because of it's simplicity.
No bloating of obsolete functions, no need to keep the plugin installed AFTER creating the child theme. It's just hit and run.
1. Install theme
2. Install and activate this plugin
3. Create child theme
4. Activate child theme
5. Deactivate and uninstall this plugin.
Plugin does the work as good as I do only in a fraction of the time.
I installed the child theme and noticed that my page size went up 33%. I checked my website and the child theme changed my cover image. I decided to delete it and go try Child Theme Configurator to see if that worked and it did.
