Couple of akragator questions

1) Is it possible to make filters like in kmail?

2) Is it possible to use the command line to make akragator download anything new then close itself

If not can anyone point to a (prefrably kde-libs based) feed reader that can do this?

As to #1 I believe it's slated but not currently available (see their home page). You could try other feed readers they may do this, I'm using Opera's feed reader and it filters better than anything else I found though it's been a while since I looked.
