is it possible to reload the content of the viewport without reloading the whole inspector.
I have found the page I want to work with under source and can save changes, but really need to see some actions that are fired on the loading of the page.
Is this possible?
you can't do that with chrome debugger tool. each JS resource will reload on page load so you will loose your change.
you can proxy tools like Fiddler which will allow you to load script from your local machine while loading a third party website. You can create a copy on your own machine and then use fiddler to intercept the call for that file and send your local copy instead
