It's ... pretty OK :-). My points/suggestions... 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.
