I also would be interested in similar functionality: the ability to list/display the most recent N episodes of a given podcast. (I can envision use-cases for displaying the most recent podcast episode, or listing the most recent 5 podcast episodes, etc.)
I would love to see any/all of the following implementations:
[powerpress latest="1" feed="myfeed"] to display the latest episode from "myfeed"
[powerpress latest="5" feed="myfeed" display="list"] to list the latest 5 episodes (titles) from "myfeed"
powerpress(latest=1&feed=myfeed&display=display) to display the latest episode from "myfeed"
powerpress(latest=5&feed=myfeed&display=list) to list the latest 5 episodes (titles) from "myfeed"
(Incorporating any/all of the above)
Note: I'll send these along to the contact form, also.
