There are a lot of valid criticisms here especially regarding accessibility but after seeing the first item be complaining about “wasted space” because of rounded corners on a finder preview it made me find it very hard to take seriously, too much old man yells at cloud energy to be honest.
These are real concerns for UI design; excessive padding, limits on information density, inconsistent spacing, clashing elements.
Does an engineer complaining about a car with hexagonal wheels have “old man yells at cloud” energy? Yeah the car still runs, and might even look cool, but it’s a stupid choice by any professional standards.
I knew at least one armchair UI expert would come out of the woodwork because I dared to have an opinion that was only agreeing with the 99% of what OP said instead of 100%, but the _level_ of obtuseness in your comment still managed to surprise me.
