Some Site Editor user-interface and block updates this month:
1. We’ve made some of the help links and buttons stand out more.
2. We’ve added a way of filtering your site’s pages by their status, and provided a little more information about pages in the main site page list.
3. You can now filter the list of documents when you’re linking to a document.
4. You can now have a button on an icon card.
5. Each card on the profile spotlight panel no longer has to link to a profile url.
6. Various small design fixes and updates.
Details in our staff blog post.
