> it's one of those things like lock-screen that Windows still does better in some ways.

Right? Unless I'm missing something, my friends and I all use a hot corner to activate the Screen Off to be able to lock our screens when we leave our laptops since there is no Win+L or Lock equivalent. :/ I guess they just expect me to close it everytime I leave? I have lots of long running stuff that I normally don't want to stop just because I want to go to the kitchen or bathroom.
