Restrict access to Pinegrow Wordpress plugin to specific user(s)

You can currently restrict access to the WP plugin by user role. However, could we have the option to restrict it to specific users? I have a scenario where the client wants admin access but I don’t want them to even see the PG plugin and definitely don’t want them to access it.

The only option I have at the moment is to deactivate and delete the plugin and then install it again if I need to make theme changes but it would be great if I could set it to only appear for my login.
