1. I've never heard of tabview and it's not on MacOS or Fedora.
2. Add ctrl-D to your possible exits. It's actually more common than ctrl-C.
3. Some of those commands are not installed by default on many systems; e.g. htop or dstat. And they require sdvanced knowledge to properly interpret. But they can be very useful. I'd suggest standard `top` and things like iostat instead.
Surprised to see this on the front page. I agree with most of the feedback and criticism here.
Hopefully some readers found it helpful regardless.
