I feel like the only dude on the planet who uses fullscreen workspaces on Mac.
The number of times I have noticed the corner of my windows is precisely zero because each important application gets its own workspace, so the window frame doesn't get rendered. Sometimes I'll tile two windows side by side on my external monitor but even then this is a complete non issue for me.
Are you guys just running everything on the one desktop workspace in windowed mode? That seems like madness.
I asked this same question years ago in one of those threads that was all windows people complaining about cmd+tab. No responses.
That means there are exactly two of us.
