for example, there are 500 news on a given feed.. Instead of showing them all, I want to see the last 5 of them

awesome.. like showing the only the latest 5 results and so on

I think you won't scare but bring additional advantages to the users. For example, there can be a button such as "additional options" to click on to set up those...

if you are planning to add additional options please consider having date and time grabbed from the feed page too

Alright, :)
