Hello, thanks so much for your work and for making it publicly available. While there are other more complex options out there, this plugin is a valuable addition to the community for those who need simple rss feed publishing.
I have one feature request: would love to be able to limit the number of items on a per feed basis. Making the feed limit a parameter in the shortcode/template function, or being able to set it in the Edit Feed Source screen in admin would be ideal.
I'd like to show a shorter feed on my front page, then link to a feed specific page that lists more items.
