suggestion for useful features

At least I didn't stumble about that being already available, if I'm wrong - my pardon.

So here my ideas:

• auto update the screen in case the coverage report got re-run or at least provide a little icon or context menu to allow a refresh. Up to now I need to toggle the package twice to get things refreshed.
• possibility to configure the coverage report generator command. e.g. in our case, we simply execute "npm test". Would be great to have a project based context menu item allowing to rerun coverage report generating process.
