Inline Editing
Lately I have been using inline editing in web apps. I really am falling in love with it. By inline, I mean the user just clicks on an object in the interface. Rather than a link, it changes a field into an edit able area, and then when you hit save, it updates the interface, all without updating the page.
General I use prototype’s form serialize and ajax updater to save the change. I like to use an abouslutely positioned dive with a scriptaculous appear effect.
Maybe later I will give a more detailed technical explanation.
