Just released version 2.2 of this plugin. Thank you to all of you who continue to give great feedback and help me in creating an even better plugin.
This release fixes some issues and improves the plugin's code, making it even more efficient and extensible.
It also includes the Italian translation, and I'm looking forward to having more translators on board to have it in other languages.
I've also set up a dedicated website http://www.wprssaggregator.com, which will supplement the documentation in this repository.
As usual, enjoy the plugin and leave feedback if you have any suggestions!
