Upgraded FlexDoc Editor

We've completely rebuilt the FlexDoc Editor to be faster, more intuitive, and more robust. This major update streamlines the content creation experience with a more organized toolbar and powerful new features, including the ability to add alt text to images, create diagrams, build more flexible tables, and add multiple pages (even pages within pages). You can still use the / command to format your content as you type, and continue using familiar features that let you embed videos, format text, and organize your content with column layouts.
