So I understand their is this option in ACP and maybe I'm doing it wrong, but I used to remember back in the day that another IPBoard I was apart of had what they called it a "Trash Can" thread that held all deleted and moved posts any MOD+ would do. Even Mybb had it and I'm not able to recreate it exactly what I wished to do if its even still possible.

Deleted content is handled in the /modcp
Have you used it? Is there something you are not able to do there?
Keep in mind that the suite handles content from various apps. A forum-only solution wouldn’t make much sense because of this.

If you did want to do something where its less clicks to move something to a forum you name trash, you could set up a saved action on forums.
