When I add a topic multi-moderation reply, I'd like to see it use the same feature as when you double post, it combines the posts...

I would love to see this implemented. We use topic-multi-moderation exensively and it looks silly when we make a post at the end of a topic then ad a multi-mod that also adds a comment.

It hasn't been really extended I think because of the lack of people showing how much they use it. Maybe 3.1 they'll expand it with variables, and all you mentioned and what others mentioned.

You mean people don't use topic multi-moderation much ?
That would be a real shame.
In all honesty we didn' use it for a long time - as we didnt quite get what the point was but now we realise what it does its invluable.
But I guess it depends on the purpose of your board and how busy it is.
