Cursor overwrite mode in vscode?

I too was missing the overtype mode in Visual Studio Code, so I went ahead and wrote an Overtype extension to add the behavior!

You can install it by opening the command palette and entering:

ext install overtype

Update: As of this writing, VS Code still does not have overtype built in, and the original extension seems to no longer be maintained. There is a more up-to-date fork here.

It seems to be working fine for me both ways I can switch it with "shift + i" on latest VS Code and macOS system.
