Thanks for contacting us here about this extension.
does the plugin show which user viewed or downloaded a single file?
This option is not implemented yet. We now can count download times for a file/category. However, the details statistic such as: "download per user" feature will be released in the version 4.7 (we are currently in version 4.5.4).
how long will it take for it to be released? because is one of the most important feature that my client needs.
Though it’s hard to give a precise date on new features release for various reasons. It mainly depends on the development roadmap we've defined for the developer and problems we may encounter during this period
