Thanks, Peter. Others have mentioned this as well. About 30 minutes ago I submitted an update that limits the extension's permissions to HN only, although it still accesses your active tab in order to place you in the right room. I'll see about a work-around for the tabs.
Ah, cool! I just assumed this wasn't possible and Chrome forced developers to do this as extensions always seem to ask for these overarching permissions when I check them out, sadly.
