datitisev yeah of course, it wasn't a feature request for this extension, but the modal thing is something that would be required to choose the destination discussion. The combination of the two is something I did not think about, but it's still a bit unnatural and probably confusing for users...
Anyway, a question about this extension: when merging two discussions, is the chronological order of the posts preserved, so that they are inserted at the right place between existing posts?
Thanks!
