Władzix – ★★★★★
“Incredible! Everything I was searching for, runs Live so you don’t have to refresh every time you edit something, very nice suggestions while typing and other small features like colors are displayed in squares while typing names. One of the best features is auto enable on websites. I have made dark theme mode for some websites, thanks to this extension! Awesome!!!”
