Expected behavior

Hi, forgive me if this is not possible to implement due to limitations, but it would be a nice addition to the extension.

I would like to be able to use any existing watch/build/serve setup that rebuilds the project whenever I save anything and serves it to a browser

And have the browser extension and VSCode extension communicate and reload the webpage for me automatically after saving any file

So that I don't have to manually hit F5 in the browser after each change/rebuild.

The way I envision it is that the extension does not serve any files in this particular scenario, but instead it opens a listening port to which the browser extension connects and whenever VSCode detects a change in a file, the VSCode extension says the connected browser extension to reload the tab it was enabled on. The port the app is served on is either known from the environment, or VSCode extension setting (workspace setting), so that when the browser extension connects, it will immediately know what tab to reload without touching unrelated web pages.
