Can I have my square corners back, please? And while you're at it, add sorting by alphabet in the WiFi networks list. Maybe even a filter field (I know, too advanced, but hey...)

No? OK, I'll skip.

you can add square corners with a terminal command afaik https://forums.macrumors.com/threads/want-the-bigger-window-...
