When clicking the Save SPF record button in the PowerSPF section it refreshes the page with the new data but it isnt obvious that this has happened as the only thing that changes is one line that is not immediately obvious.

Perhaps a pop up box in the middle of the screen could be implemented with a green tick in it that either disappears automatically after 2 seconds or has an OK button to close it?

That would then make it far more obvious that something had happened rather than leaving the user possibly confused if the record itself is long and the extra entry on the end of the string doesnt appear on the screen.

Hovering over the entry could also then reveal the entire SPF record just for completeness and those of a fussy nature like myself that want to be sure all has been recorded.
