You can save and reuse layouts by saving page sections:
- Hover over a section and click the heart icon to save it. 
- Add saved sections via Edit > Add Section > My Saved Sections. 
- Note: Saved sections are independent of the original and retain design and content but may require manual setup for features like forms. 
- Saved sections cannot include collection pages or footers.
