in thread Update post date after edit

...a post highlighted itself somehow (an asterisk or similar) to indicate...

I would suggest to tag an updated node using CSS class attribute (i.e. updated) with a sensible site-default:

<div class="$AS_BEFORE updated"> ... </div>
Now, every monk can fine-tune the layout using own CSS redefinitions (Help for Display Settings). Something like i.e.
.updated { border-left: 1px solid red; }
.updated::before { content: "UPDATED: "; }
Perhaps add ud-$YYYYMMDD or updated-today or similar for more customisation options?
