Its funny how we all differ in respect to what kind of feedback we find acceptable from our computers. I turn off all audio notifications. I MUST have a hard disk light. I need graphs running at all times. I like to hear fans spinning up when the CPU/GPU is hot. And I never want to have my computer talk to me. ethernet jacks MUST have link and activity lights.
This is the way.
My keyboard came with RGB. I don’t care for it but I let it light up if any kind of lock is engaged and it glows a low red colour beneath the keys that I click.
That’s the only step I go beyond you. And the only reason I did it was because no lights at all for the keyboard meant cycling through every possible setting.
My computer is a machine. Its beauty is in its functionality. Being able to look at it and know what it’s doing is important.
Once every 2 years I gotta do data entry with something that can’t be OCR’d for whatever reason and I need those keys.
I regularly use the numpad, often in the context of a throwaway spreadsheet where I'm doing some napkin-math. (Or sometimes a tiny Python script, depending on what needs modeling.) Not true "data entry' in the "finish these X pages" sense, I guess.
