Suggestion

Hi, I am a avid user of your domain mapping plugin, but may I make a suggestion for improvement? It would be great if the changes you make on the plugin page, would not be saved by ajax, but by an old-fashioned save button. Too many times I wonder if the changes I make are saved or not, especially when doing multiple actions.
Sometimes I think I have deleted a domain, but then it seems that those changes haven't been saved and I have to go back and delete it again.
