Great! Just wish it had a few more features.. This is one of 3 extensions that will sink my data to the account, so that it's available on my other machine. I have installed and tested ALL CSS and JS editors. Thank you!! Please, consider adding these features: - Add a tab for CSS - Apply CSS immediately - Dark mode - Option to move the window around and resize it, like this extension does: https://chrome.google.com/webstore/detail/live-editor-for-css-less/ifhikkcafabcgolfjegfcgloomalapol
