A field for user-defined classification/category/type on Skuid pages

You should be able to add a custom field to the pages object.  Then you should be able to create your own version of the Pages list page (Not in the Skuid module)  The object is managed and so I’m not exactly sure what happens to your custom field when you install an upgrade of SKuid.  But hopefully you’ll be good… 

I may use this technique in future implementations.
