MDG Option for WP Cron - Auto set real Cronjob for like every 5min and deactivate WP Cronjob
This already happens. It's set to hourly on a randomised minute. You can adjust under "developer tools".
MDG Create plugin kits with own plugins we can deploy to sites
This is coming very soon, we're just finalising the UI for it.
MDG Clean up feature like in runcloud to clean logs and free space.
Option to activate/deactivate search engine indexing
Option to deactivate common WP security risks like xml-rpc , XSS etc.
Possibility to deploy staging sites on customers own domains.
These are all good suggestions and will definitely be possible in the future.
