Hi @Julian Matthews, The vscode-objectscript extension has had this functionality for years. Unfortunately it requires installing a version from GitHub instead of the official marketplace due to restrictions from Microsoft. Guillaume calls this out in his "Why This Extension Exists" section. Our README gives the steps for enabling the feature: https://github.com/intersystems-community/vscode-objectscript?tab=readme-ov-file#enable-proposed-apis

@Sergio Mundarain Can you please open an issue on https://github.com/intersystems-community/vscode-objectscript/issues with screenshots and steps to reproduce your issue?
