The feature that keeps me from moving off of vscode is their markdown support. In particular the ability to drag and drop to insert links to files and images *. Surprisingly, no other editor does this even though I use it all the time.
I took the plunge and don't regret it. Despite the condition of the web site the extension is very useful and relatively free of any annoying bugs.
At some point in time, I'd like to take the time to invest building a custom version of the extension to bump dependencies to access more modern support for plantuml/mermaid diagrams.
I belong to the class of people who believe in customising their tools as they please. So I'd have written an Emacs package to do this. But then again, this is Emacs, so someone's probably already done it. Oh, here it is: https://github.com/mooreryan/markdown-dnd-images
