Is it possible to customise the quick info section in the content editor to show additional information about the item? Thanks
I think this would be quite tricky. If you look at Sitecore.Shell.Applications.ContentManager.Editor
(in Sitecore.Client.dll), you'll see there is a RenderQuickInfo
method. The HTML gets pieced together manually and is added to an EditorFormatter object as a literal control. All the classes involved are tightly integrated in to the application - there's no easily identifiable customisation point.
There are some pipelines associated with the rendering of the Content Editor,
But I don't think these will provide an easy way in.
In general, I always think that if Sitecore haven't made part of the application easily customizable, then they probably did it on purpose.
