Hi Brett, thanks for getting back to me with an answer. As we have thousands of routines containing dot syntax I couldn't really leave this without a solution. For now we've built our own simple extension to implement OnTypeFormattingEditProvider. See https://vshaxe.github.io/vscode-extern/vscode/OnTypeFormattingEditProvider.html.

In our case all the method implementation needs to do is look at the previous line, assess how many dots the line begins with and populate the same on the new line. I can appreciate the difficulty you'll have with making this work for all scenarios in Object Script though.

Hi @John Murray, thanks so much for this. I can confirm that this fixes the issue.
