One thing I am looking forward to from Edge is an overall improvement on the developer tools. There is always room for improvement and I wish Mozilla would focus more on theirs too. Theres things we probably have yet to consider and next time I hit a mental devtools roadblock I will write it all down into some sort of blog post because we can totally do so many awesome things with devtools I think. If anyone can make it amazing I know Microsoft definitely can. I still found it incredible being able to debug Chrome from VS Code.
