Hi, I couldn't find what you're after, but have you tried the "Advanced configuration documentation" at http://codezen.org/canto/config
? You might also like to check out newsbeuter which is also a console feed reader (which I use) which has a nice simple interface, with a feed overview, it's not as customisable, but that might be ok depending on what you're after.
If you have a question that has been answered and solved, then please edit your original post and put a [SOLVED] at the end of your subject header
Hint - use a google search including the search term site:forums.linuxmint.com
