Sort by getting date and tome
Sometimes new posts are below the posts I have marked as unread (I have the reader set up to show unread posts only, newest on top).
It seems, that the items are sorted by the date and time the item was created and when the feed is read and contains posts older than the items I have already seen, then these older posts go below the posts I have seen.
Then, to read newly found posts I have to scroll down and again mark the posts I have seen before as unread.
Would it be possible to add an option to sort by the date and time the reader has found the posts instead of the date and time the posts were created?

This is now the default sort order.
