@User looked into setting colored tabs based on schema.
tldr: customizing tabs is rather limited. you can only set the color of active/background tabs and there wasn't a way to change the title (that I could find)

let me know if this would still be useful. if anyone knows how to update the tab title in vscode, input appreciated 🙏
