When you have both Links and Tasks open, one will be blurred. (This new “feature” was introduced in 2024.) Personally, I hate the way this looks - it makes my eyes hurt. Also, you have to click on the blurred list to unblur it, but it’s hard not to accidentally click on a (blurred) link. Then, you lose the list altogether as your window has gone to a random link. I use both lists so I don’t want to hide one just to avoid the blurring.
Am I the only one who doesn’t like the blurring and wishes they would revert to a pre-blur version?
