Thanks for the quick replay gandalf, glad to hear its already under consideration. I wasn't thinking about staking with ring signatures, that would be awesome! Maybe to start, jbg could leave staking as it is, but make ring sig the default tx mode. That would cause ppl to have to move their coins to their public address before being able to stake, so not ideal but a first step. Just an idea, I'm not fluent in c++ but know enough to realise "simple" things are rarely actually simple.
