You've selected some use cases designed to show that VSCode is inferior to emacs. What you failed to realize is that your use cases are invalid for probably a vast majority of people:
> Read, write and send emails
I prefer to do that in a dedicated app that actually knows how to deal with emails, and not from inside my text editor/IDE
> can I quickly write something that will read an email, and then go and add a TODO in the appropriate section of some document based on the contents of that email
I tend to prefer not to spend my time programming things, but, you know, enjoy life.
If I need a todo from an email, I'll copy paste it to an app that, for example, syncs to my phone
The previous user said that you can do "literally anything" in VSCode that you can do in Emacs, I think these examples were chosen to prove that statement wrong. It doesn't mean that Emacs is better for everyone.
Because I need a file manager? I can give you an example of a time where I needed to examine some files, and depending on what I saw, with a keystroke make notes in a text file with links to those files, but that's secondary to the topic. The simpler answer is that I need things like file managers and window managers, and Emacs is both. Viewing Emacs as a text editor is a misconception you seem to have.
My question was whether there are plugins for VSCode to do any of these. You did not address that at all. Your comment is noise in this thread.

> Use it as a window manager
Why?
> Use it as a file manager
Why?
