I decided to open the PR, so that we can comment on something, rather than just imagining it. Configuration and wording is not final, so yes - I await your comments.

Does this support debugging the daily index.ts files? I added following to my launch config just to be able to hit f5 on currently open file. Battled a few issues, but seems to be working pretty solidly now:

{
    "version": "0.2.0",
    "configurations": [
        {
            "type": "node",
            "request": "launch",
            "name": "Launch Program",
            "program": "${file}",
            "preLaunchTask": "tsc: build - tsconfig.json"
        }
    ]
}
