View two notes side-by-side
You can view two notes, side-by-side, by opening a second note under Copilot in the right sidebar!
To open a note in the right sidebar, hold down OPTION (Mac) or ALT (Windows) while clicking on any note listed under your Pinned or Recents section in the left side of the app.
You can also use this same action to open a mentioned/linken note in an open note.
