(sorry for my english)

I recently bought a Raspberry Pi 3 model B to use it as a web dev server for home and school. Actually, when Im at home, the pi connect to my home wifi so I can easily use it with the local ip adress; I have a complete web server installed and an FTP server. I have 2 problems at the moment :

1. When I turn off the Pi, I can't really know if I can unplug the power wire or not yet. So my question is: Does a web terminal is the solution? I would like to have shell output like I was connected to HDMI to know when the Pi is really off; Pretty sure that's impossible since Pi shutdown wifi/router service before shutdown himself.

2. When Im at school, I have to connect my laptop with my Pi as ethernet so any of them has internet. I would like to connect my laptop to Pi as wifi (Pi as a router) and connect the pi to a wifi at the same time to get internet (atleast for the pi, I don't really need internet on my laptop).

Thanks for help!
