It's the same as you have an engine temperature gauge in most cars. I'm not really interested on what's going on inside the engine, I just want to know if the engine overheats so I can check basic things (cooling system leaks, etc) and if I cannot see what's wrong I wait and try to get to the nearest garage or call roadside assistance.

As a power user, I see value in a process list but I see why it does not take priority over other features.

Edit: spelling
