Today Microsoft released the Visual Studio Code file/folder editor.
The first limitation is it appears to be a single-instance application.
Is there a way of getting multiple instances, or otherwise having it open multiple folders simultaneously?
Ctrl + Shift + N will open a new window, while Ctrl+K then releases the keys, and pressing O would open the current tab in a new window. You can then use menu File → Open Folder to have two instances of Visual Studio Code with different folders in each window.
⌘ + Shift + N and ⌘ + K for Mac.
