Often when we're building pages, we want to reuse the structure of a section in another page and then tweak just a few things. It would be a game changer to be able to clone a section on the same page (which should have pretty low LOE), and then also another page (might be bigger LOE).
Other page/email builders have this typeof functionality. I'd image these being little icons that show up when you hover over the section.
Copy: Just duplicates the section under the current section you're hovering over.
Copy to: lets you pick another page, then copies it there and opens a new window to that page.
Copy from: Eventually could have a copy from but the UI for that would be a bit more complex so way less critical.
