I have something which I've tried to open in Write, from the journal. I'm not sure why, but Write never finishes starting. It keeps pulsing in the Home view.
This made me realize that there's no extra/external way to kill an activity. While Write was pulsing, I couldn't stop it, so all I can do is leave it there until I'm ready to reboot. I expect there will be other circumstances where I'd want to kill an Activity, also.
Anyway, I suppose this is a feature request.
