Allow the tab to be reloaded from the JSS Browser buffer

[Wilfred]

It would be nice to have a button for reloading things in tabs, so the *JSS Browser @127.0.0.1:9222 showed the following:

B9727C08-E0C4-12C9-C7FA-B912B24F721E.Google - https://www.google.co.uk/webhp?sourceid=chrome-instant&ion=1&ie=UTF-8
  [ open console ] [ reload ]

It would be brilliant to have an explicit 'reload CSS' button too.

I've had a look at writing a patch, but I'm struggling to find my way around the jss codebase. I can add buttons to jss-browser-mode-refresh with jss-insert-button, but that's expecting a command rather than a function. There's jss-console-reload-page and jss-tab-reload. I think jss-tab-reload is what I want, but I can't see how to tell jss-insert-button to pass the tab to jss-tab-reload.

Any tips? Is this a feature you'd be willing to accept, in principle?
