It’s a creature that comes from an environment where we cannot survive, and drags us back into its realm to eat us. I was thinking more the kraken, but maybe ‘space cthulhu’-type aliens work too.

Don’t think Bigfoot is a particularly violent chap? Maybe a Wendigo might be a better match.

Only has the functionality that you need, everything is obviously in its place. Runs incredibly quickly without using a lot of resources, and then gets out your way when you’re trying to do stuff. No settings hidden away because they might confuse novice users. No bullshit shoehorned in by managers.

Apart from the ugly font rendering, this might be as good as the Windows UI ever got. WinNT looks the same and has almost incomparable stability improvements, but only if you’ve the right hardware to run it. WinXP starts the downhill slide with ‘appearance over functionality’ and the hot mess of the control panel.

I could live with how OP has things set up here; my own copy of Plasma doesn’t look a million miles from this.
