Sonoma Safari SideBar Peeking When Hidden
If you are like me and you do not use Safari's sidebar this new Sonoma behaviour will annoy you too.
When the sidebar in Safari is hidden... putting the mouse near the left edge of the Safari window will shift the webpage's layout a bit to the right... and the sidebar will peek out a bit, as if to show that you can drag it out should you want to show it.
It is very annoying to see the whole screen shift a bit just because the mouse pointer happens to be there on that. Personally I often put the mouse pointer there when I am watching a video on YouTube... having the screen shift is frustrating.
I hope they stop this behaviour, unless I am the only one seeing it and then it is a bug or glitch.
