Add link for Classic aggregators' feed

Hello,

I'm trying to create a website (basically a feed aggregator) and using "Aggregator Items" processor within the module.
But all I get are a feed posts hidden somewhere and accessible only by direct link like "aggregator/sources/2".
How can I push all that post on the frontpage? There is no node types binded with "Aggregator items" processor and "aggregator-items" type is used only for "Nodes" processor (which also is very confusing for user in terms of drupal core features don't want to get feeds in blogged way). That's confusing beside having strange auto-filled categories within "Aggregator items" posts that have broken links like "aggregator/categories/5" pointong nowhere. I've 2 vocabularies installed - for Feeds and for their Items.

Also I have an error each type adding the new feed, as I get that's a lack of function at my hoster server, what this? Please can you help on it? Maybe this cause strange behaviour of "Aggregator items" processor?
