I am currently using the basic RSS widget to display summaries of my 5 most recent blog posts on my home page. I have several other domains and would like to have a similar display, but only of posts appropriate to the subject of that page. I would like to use either categories or tags to segregate the appropriate posts. Is there a plug-in or widget that will display posts by category or tag? So far I've installed four plug-ins that all looked promising only to discover that each in turn does not do what I want. Looking for something a little more solid than another shot in the dark.
