(Feature Request) Keep the title when adding notes

[manto89]

Summary

When using the Save Link with a Note i want to add some custom text while keeping the page title.

Current Behavior

When adding some text to the textarea in Save Link with a Note the page title is lost, the first line of the textarea is used as the note title, the rest as note content.
If the textarea is left empty, the note will have the page title as note title and an empty body.

My Proposal

Keep the behavior as is, but add a checkbox under the textarea to keep the page title as note title. In this way all the text in the textarea will be used as the note contet

Additional Note

I already worked on a PR for this, will link it asap
