Regarding the description of your plugin, I think it's more idiomatic to begin with option and then shift (see screenshot), but I'm nitpicking, and it's your plugin so your call.
Regarding adding Alcatraz to the list of plugins, it should at least been a separate PR so we can discuss the pros and cons. The removal procedure is described on http://alcatraz.io/, I'm not convinced there's a use case for desinstalling Alcatraz from its own interface.
Installing Alcatraz with Alcatraz wouldn't really make sense, because then you'd already have it installed right? :)
