How content block titles work
pootle page builder has something we call 'Smart titles'.
This means that each content block is updated with the title auto-magically so you can see what content is where.
For example, if you use some text for some content you will see the text. If you use a video, it will say Video and where it's from. For an Image - the image alt text. Shortcodes too.
Over time these will get even smarter!
