For some reason, that option was greyed out until I turned "Keep EH running in the background when I quit EN." I had to turn that option on, then turn the other two off, and then turn off the "keep EH running" thing again. Weird interface cues there, for sure. Somebody needs to fix that. As for the "to show you EN is running," I'm pretty sure that's what the Dock is for. The growing Mac app tendency of "hey, let me stick something in the Menu Bar by default" is even more obnoxious than Win apps longstanding tendency to drop icons on the desktop without asking.
