Now I only hope they add in hot-disk support.
Sublime Text 3 checks to see if the currently opened version differs from the file system. If it does, it prompts the user to keep the current version or replace it with the disk version. VS Code just replaces the current version with the disk version and doesn't retain history so you can't undo this.
I lost about an hour of work yesterday because I had a file open in both VS Code and Sublime Text. Pressing save in Sublime Text wiped out all changes. :(
VScode and Atom are constantly receiving new features. So we can say that they are still in beta too.
Beta is just a word.
BTW, really awesome job VSCode team :) I love what you're doing!
(I use it to edit a very large JSON test fixture file)
