I am using the Core Aggregator module to aggregate content from RSS feeds, and then using a View to output the content.
The Aggregator module has two view modes, default and summary. The view modes themselves are editable, but the feed items themselves are grouped into the "items" field, that has no options.
In default mode, the title, blog, description etc. for each item are rendered, but in summary mode only the title and blog name are rendered.
How can I influence the fields that are rendered in summary view mode?
