Updated to BAD not working (as it does not work in Google for me and the github report has been marked as bug but not resolved for a few months). It'sa great script but not if not working at all.
Options not showing anywhere on Google Search page
Could be my installation of course, maybe someone else can confirm. Running latest version, tried to re-install it but I can't seem to see the options anywhere right now when I do regular Google Search (likely a quick fix pending it's an issue for everyone).
