[Feature Request] Seach and Replace and Save Project As

Hi all

I'd love to see some basic fundamentals such as being able to search for strings and replace them en mass, as well as being able to Save As, rather than just Save.

Thanks

The request covers two separate editor entry points: searching and replacing strings in bulk, and saving a project under a new name. Start by finding the existing Save behavior and the editor's text-search handling. Done should include agreed behavior and tests for both requests, but the issue does not define their scope.
