Correct! When logged into the interface, you can easily disable blocking with one click, for a set amount of time. FWIW, I sourced multiple public blacklists/whitelists, and did as much research as I could ahead of time to research devices I routinely have on my network vs any issues PiHole might have with them, and was sure to add any necessary sites to the whitelist when I first set them up. It was really easy for me and I've had zero issues since (YMMV).
