@ctietze yes, it _is_ obvious to have a preview for mass text edit replacements. This is one of many reasons why I dumped #Emacs for #jEdit ~20 years ago.
Unfortunately, jEdit never became a full Emacs replacement, but close enough, and plenty of others since that have improved the art.
I've only recently re-adopted Emacs for #OrgRoam and it has been deeply frustrating. At best Emacs is an editor toolkit, and org-roam a #PKM toolkit, but I am persistent.
