Controlling WordPress themes at the same time is one of the key features of the MainWP Plugin. MainWP Plugin allows you to manage WordPress themes across your Child Sites from one place, which results in a huge time-saving.
By using the MainWP Plugin, you can install a WordPress theme to multiple websites in less than a minute. You can also activate, delete, and update themes on all your websites at the same time.
That is not all, MainWP Plugin will allow you to set automatic updates for WordPress themes that you trust. Once you enable the feature and mark the “trusted” themes, MainWP will do the rest.
