I know that in settings I can make it so that when I am on someone's computer, I can black out the wallpaper, that way they know I am there. But I want to be able to know when someone is on my computer? If I leave and comeback, unless they have mead the setting on their side to black out the screen, I would not know they are there. I would just like to know when someone is on my computer . A small screen in the bottom of my window or something. cause as it stands, anyone can come in and I would not know. I know they have to have my password. But, It is just nice to know someone came in. Is there a way, that I am missing?
