How can I change the sorting order?

[DRN88]

It is a nice reader. But I cannot seem to find how to change the sorting order to Ascending (Date). All the rss items are from the oldest to the newest. I want to see the newest on top of my list.

How can I change it to show newest first?

I have the opposite problem: I see the newest at the top and I want the oldest...
