Inconvenient backup and restore of Sites with Catalog Connections to different URLs

Using Catalog Connections in SharePoint 2013 offers great flexibility with regard to content reuse within as well as across Farms. Unfortunately, as Catalog Connections are based on URLs, they break if you restore your Site Collections to different URLs. So is rebuilding Catalog Connections the only option or is there a better way to work with Catalog Connections and backup and restore of Site Collections to different URLs?

Easier working with size-based Image Renditions in SharePoint 2013

By default when applying an Image Rendition to an image, SharePoint references the particular rendition by its ID. And although it works, it introduces a number of challenges. Although you could manually change the ID-based reference to size-based manually there is a more convenient way to get this done.
