"Improved error formatting in JavaScript and TypeScript" is a bug I filed with them over 4 years ago.
I had the genius idea that you should be able to read the error messages, especially when it was related to types. The previous output was almost unreadable.
They finally agreed to add it after someone built their own plugin to do the same thing in VSCode.
A bit frustrating that it took this long, but glad they did it. Over the years, I've tried every IDE on the planet (I have no religious notion of the best one), and this one remains my favorite simply because it works very well across a lot of languages and because they do listen to feedback in their issue tracker (eventually).
