When you want to create a staging site via the MainWP Staging Extension, you get the following notice:
It would be great if there’s a button available, that directly installs and activates the WP Staging plugin on the child site, so you can continue via this screen and don’t have to go to the child site or Install Plugins screen and resync the child information.
I’m not using the Pro version of WP Staging, but a bonus could be that the Pro version of the plugin is installed if a license is available in the MainWP Staging settings.
