Live Server please help configuring

Installed Live Server. It works but have two questions:

  1. How can I obtain a start and stop Live Server when I right click on an HTNL page? This is the behaviour I am used to from Visual Studio

  2. How can I change the default starting port from 3000 (which conflicts with node.js/json-server) and set it to say 5000 or 5500?

Mac OS. Atom 1.53. Live Server 2.3.0

Thanks a lot
