Limitations of the WP RSS Aggregator Widget

The Widget add-on was developed a while back for a specific use-case, and as a result, it is limited in its functionality for the time being. It may be improved in the future.

Here is how the WP RSS Aggregator widget is limited.

1. The Widget can only display all imported feed items. 
2. The Widget cannot display feed items from only specific feed sources.
3. The Widget add-on is not integrated with the Categories add-on, so you cannot use it to display a specific feed source category.
