UI: Extremely simple. No unnecessary objects. But some people might want more. 4/5
Core: Not bad, but lack of ignoring protocol may drive people away. 3/5
Text: Some critical grammar errors can be found in screenshots and texts. Ask your friend to fix your English. 2/5
Overall: 3/5 - not great, not extremely bad, but "good". You can do better.

Basic but good add-on ! :)
Wish some features like possibility to use wildcard and/or regex in whitelist , whitelist directly from the icon, export-import list.
Cheers, inducements, encouragements :)
