Is there a way to customize the Action Panel page? I would like to add a preview option to it.
The Action Panel has 2 basic parts: a JSP page located at
and an internal stylesheet which is located at
If you just need to modify styles, banners, etc, you can do this with the JSP page. If you need to add a new preview option, you need to dig into the stylesheet.
Of course, these pages were not written to be customized, and none of your changes will be preserved on upgrade, so make sure you have good backups of your changes.
