Add functionality to install, modify and manage wordpress or joomla via API
Right now you can set a service plan to have WordPress or Joomla pre-installed with any new subscriptions, however the installation data such as admin usernames, passwords, site titles are randomized more so if the subscription/domain is setup via API. I think it could be nice if there was an option to install them with custom data or customize them via API. such that when installing via API, i can explicitly set the site title, admin username and passwords, database usernames and passwords etc.
WPT v6.0 adds REST API for the majority of WP Toolkit operations. Please file a separate request for Joomla, since it's a different project. Let us know if you have any feedback.
