Add ability to detect new local files and mark for publishing automatically.

I would love to see the ability for Coda to detect when a new file has been added to the local site folder and mark it for publishing.

For example, if I wish to add an image to a web page. I have the original image open in Photoshop where I shrink it to a web friendly resolution and then use the Save for Web... option to save the shrunk image in the site's images folder.

At the moment I now need to manually find that file in the navigation pane of Coda, and mark it for publishing myself. When adding lots of images it gets tricky to remember which ones are new. So if Coda could automatically recognise that I have added a new image file to the site directory and automatically mark it for publishing, that would make many people's lives a lot easier!

Thank you!
