There's enough tooling as it stands. In-browser devtools are a veritable kitchen sink of possibilities to tap into. And even a cursory glance at some open source projects on Github yields a plethora of tools, modules and snippets of code to use in your project. In essence you can do anything you want with some JS, CSS, and HTML. This is the beauty of the web. We get lost when we ask for more tools and techniques to do things. It's like a massive collective hallucination that the current stack(s) for developing are unworthy or need to be drastically improved. Yes, progress is good, but we've reached a tipping point IMHO.
