It’s always good to look at the other side (Intellij Idea) sometimes and there are few good things that could dramatically improve production imo on the html side:
-One of the best thing on the html/css side of Idea is that it is aware of your content, meaning that it can autocomplete id and class attribute for a element in an html file, it can auto complete src attribute of images and once choosed, auto complete height and width too ! This is time saver, how many times you lost checking dimension of images, good spelling of your id/class css styles etc…
Of course since it is aware of your html content, it can tell you unused css class/id, refactor id/class name etc….
-A custom image decorator appending the dimension of the image after the name in the navigator view would be very usefull too.
