Would you be open to revisiting this? It would be great to have it as part of the officially maintained repo. And it wouldn’t / shouldn’t add any issues or instability.
My use-case is meetings, where we use an Event as the OP, and the minutes go in a new post somewhere below it. It would be great to have TOC available to be applied to minutes.
I would not want it to apply to all posts - that would get unpleasantly busy very fast!!!
