Find and Replace across all notes

All notes would be amazing: use case replacing old @name mentions with eg 'Client Name' so I can still find person in search, but they don't show up in Mentions.

Can this be done in iOS and iPadOS?

Have adapted the request to cover all notes.

It exists already (as Dan says), but I'd love to have it upgraded to operate over any notes in a folder, or the whole base. As a further workaround when I need to do this, I open the folder in Visual Studio Code, which gives me this function.

This exists already. Try `cmd + F` on a note. That’ll open the find bar. Beside it there’s a checkbox for “replace”, which will show another input field for what you want to replace things with. And an “All” button go replace all instances at once.
