Thanks a lot for this great development.
Thank you for the review ieng!
I myself had wondered about it for a long time and had even suggested something similar be built to the Joomlatools crew some time ago, but I finally decided to sit down and write it a few months ago for my own usage.
The main thing the plugin saves is time, because it finally allows the listing of documents from one or more DOCman categories to be automated with a content item in your page. Now all your users (or you!) need to do is upload the document, make sure it gets published/approved, and your content item will automatically be up to date with the latest files, which to me is the whole reason for having a system like DOCman in place :-).
Additionally, I wasn't aware of this until earlier this week, but the Custom HTML module within Joomla does not allow content plugins to be processed so I've modified an existing Custom HTML module (built by Dart-Creations.com) so that this can be done:
You can see an example of the plugin being used within a module on the demo site:
Hopefully that will be helpful for some users visiting this page :-).
Thank you again for your review and if there is anything else you feel the plugin needs, feel free to let me know and I'll do my best to include it in the next release!
