When I enable this plug-in, I've observed that the Multiquote ("Quote") and Reply buttons on posts disappear. I believe that's expected behavior, but when I then
disable the following option:

..the Quote and Reply buttons are still missing, meaning that it is no longer possible to directly reply to posts at all. Am I missing something? Do the other settings matter for the purposes of displaying the Quote/Reply buttons on posts?
EDIT: So I believe I've figured this out. If a user doesn't have the "Can comment on post" permission enabled, then the Quote/Reply links are removed as well as the Comment button. I would argue that this is a bug given that commenting has nothing to do with quoting a post, and a permission that explicitly controls 'commenting' should not affect quoting at all... but at least I know that you can ensure those options are presented.
Just to illustrate how this can inhibit use: I was hoping to test this add-on with my moderator team on an internal portion of my forum, before deciding whether or not to roll it out sidewide. However, given this bug, in order to do that I would have to remove the ability to reply or multi-quote for everyone else in my forum. Needless to say, that's not really acceptable.
