Sandbox Editing Mode

From old feedback: Sandbox Editing Mode | Cwicly

A mode in which it’s possible to edit a live website and to later apply those changes. This is a nice to have feature that would be particularly handy on a live website with lots of visitors and/or those sites which have a lot of database use for example purchases via Woocommerce.
It would also be useful where the hosting doesn’t include staging.
This would I guess be limited to editing those things that would not to break the site such as appearance and layout etc.
