Every now and again I visit Arvind Satyanarayan's blog just to see what latest goodies he has come up with. After using EnhancedEntryEditing and SCode, He now has LivePreview. You can read about it here .
The long and short of it: It allows you to preview the Entry Prior to publishing. This saves a lot of time and effort. Like his other plugins, fairly straight forward to set up.
Music I'm listening to now:
"Wisemen" by Jame Blunt from his "Back to Bedlam " album.
