Symbols are great but sometimes you just need to copy a few html elements from one or more pages into a new page.
What if you could see another page's navigator panel without ever leaving the page you're working on?
Just click to copy and paste it back to your page.
(You're not editing the page, just copying some elements from one page to the other without having to load another page).
This would save development time and require less data transfer from switching between pages as you could compare the html structure of multiple pages without loading each one of them (and then loading your page again).
