Using the Jentla Manager GUI, it is possible to review all extensions on sites under the control of the Jentla Manager. Components, Modules, Plugins, Language Packs and Templates can all be installed/uninstalled, enabled/disabled, centrally. We are working on centralized management of section level templates.
Our goal is to be able to manage all aspects of independent Joomla sites from the Jentla Manager. The vast majority of site management can now be completed centrally. The remaining aspects of extension management, like updating configurations on complex site components must be done by logging into the site.

Business benefits of Extension Management
Massive business process efficiencies are created using Jentla for extension management.
Many processes which currently take an hour or more per site can be achieved in less than a minute across hundreds of sites. Jentla becomes a business framework that enables anyone charging for support to scale, lower costs and increase margins. Jentla has the ability to become a truly disruptive technology in this environment, redefining the boundaries and costs of support. Early adopters will enjoy a compelling competitive advantage over any businesses using existing manual processes.
Simple Site Creation
Being able to quickly and simply replicate a site is probably the most powerful tool to compliment Joomla systems. It allows any organisation to quickly copy a site similar to an existing site (with or without the content data), this site can then be customised to the reflect any new requirements and deployed.
In this way hundreds of similar sites can be created retaining core branding but with different content. This could be particularly important for industries such as the real estate sector where thousands of similar sites could be created and deployed in a fraction ofthe time and at a fraction of the cost of any other system
With batch creation using a CSV file, we comfortably put 1000 sites live in 6 hours.
