I would also praise this feature as I am coming from the php/html/css coding world but wanted to have an easier way of following good practices, patterns, standards on the websites I develop. With Bricks I have the ability to fine tune everything I want I don’t have to worry about the underlying skeleton. So having a css/html editor that reflects the visual editor and vice versa would be a huge performance upgrade for me.
This is somehow similar to my other thread: Is there a centralized class editor? But this thread is more precise so I link and follow this instead.
