Maybe I'm just thick, but I don't find Preview on macOS simple or easy to use.

What the hell is “Contact Sheet” and why should I have to care about this jargon?

> And man, is it hard to use for just normal everyday use.

This is how I see macOS. I've used it at work for 3 years now, and it still gets in my way every day.

I accept that some people like it, but it's very much not for me. (I suppose I “think differently” from Apple's designers.)
