I've lost count of the number of times I accidentally grabbed a tab in a #macOS Finder window instead of the window's title bar if I want to move that window.
It is simply beyond comprehension, IMHO, that the #UX designers at Apple decided to remove any and all #affordances that clearly separate the tab from the title bar area.
And I fear that this aesthetics-over-usability mindset will dominate even more in the redesign announced for #WWDC2025.
Well, one can always hope…
