If you want to use Monologuing on your own instances, I've split it out of my own branch and made a fork of 1.1.2 with the feature added. You can find it here: https://github.com/STJrInuyasha/mastodon/tree/monologuing

I should probably mention that the monologuing branch has moved to "feature/monologuing" for organization purposes.

Also, it's up to date with 1.5.0, woo
