... Elxis version 2009.3 codename Aphrodite is out, download it from Elxis Download Center (EDC) ...
From Elxis Official Documentation
Elxis 2009.0 or newer allows you to install extensions (templates, modules, components, etc) directly from Elxis Downloads Center (EDC) without downloading the extension in your computer and re-upload it in your site. EDC installer also allows you to browse in real time the available extensions at elxis-downloads.com.
When ever you go to an Elxis installer (modules installer, components installer, etc) you can click on the Fetch list of available extensions to get a list of the available extensions of that type from EDC. The extensions are sorted by date descending with the latest additions first. EDC installer will also show you some information for each extension, link to the extension's detailed page at EDC and links to download and install the extension. Just click install to any of these extensions to install it. The one-click download and install feature of the EDC installer is one more powerful yet simple to use feature of Elxis CMS.
Since Elxis 2009.2 the EDC installer will also inform you if a listed extension is already installed and in that case instead of providing a download and install link it will display an uninstall link. By clicking on the unistall icon the extension will be removed from your system.
