Suggestion

In the last version, the rss reader only has one option for maxiun number of articles of per feed. So when i set a number larger or smaller, the rss reader will show old torrents or icorrect items.
I wonder if it's posisible to let the rss reader automatically culculate the number? Or at least fix the problem i mentioned and add the ability to set the number per subscription.
If the problem i mentioned does not exist juse because i set it up incorrectly please point me out.
Thank you for your efforts and your generosity.
