List Properties Feature
Here is my first feature. This feature lets you inspect the various properties of a list, ranging from general properties like title and id, to the fields, views, content types attached to the list and even the workflows activatd on the list. All properties are listed in expandable sections:
The feature is a site collection feature and must be activated on the Site collection features page:
When the feature is activated, it is available through a link on the List Settings page.
As you can see in the first image, there are a lot of links on the page from where you can navigate to the different OOB SharePoint pages to modify the list, its fields, views, content types, workflows etc.
This version of the List Properties feature is makes use of the SharePoint controls and a code-behind assembly that is deployed in the Global Assembly Cache. (instead of a lot of HTML tables and elements that were populated with inline code like most of the OOB SharePoint pages).
You can download the feature here.
More documentation on the feature can be found here.
