Instead of creating filters through comboboxes in a GUI, it would be very powerful to have a "Filter stript editor". It coud use the existing JS engine and expose special objects and methods in it for filter development. Something like:

if(mail.sender.contains("osama")
	mail.trash();
if(mail.sender.isInAddressBooxFolder("friends"))
	mail.moveTo("Friends");
if(mail.subject.contains("[KDE]") && !mail.hasAttachments())
	mail.sendTo("KDE Development");
