I'm not quite sure what you mean about only implementing this for v2--it looks
like you've implemented it for both. If you are intending to keep this in the
tool-bar, I think you should move it to the Screen Options menu, since there
isn't much horizontal space, and this takes up quite a lot.

Yes, I started with the v1 app, but we really want it in the v2 app removing
this.
It'll only be visible for hosts that were specifically run with this debug
option, so I don't think that's an issue.
