I am pretty sure that by default i used to have a bar item that when i expanded it contained all of the newest articles from an RSS feed as clickable links, each link was the name of the summary.
I have no idea how to recreate this for my own use.
for example, on my bookmark bar, i'd like a folder called PSP, then a folder called RSS (News), then inside there 4 folders, each linking to a different news site, when i approach the folder for each news site, i would expect to see that day's articles listed, not just a hyperlink to the actual RSS feed. I have looked through the help file and options i could find in safari, but i'm having trouble recreating it.
