Dolphin > General is probably not the right product/component, but I don't know where else to put it ;-) Sometimes, when I *manually* activate standby, I forget that I have an SSH session open (which is then broken after wakeup). When doing a shutdown/restart, there is a screen with a 30 seconds countdown. So I'm suggesting to show the same screen when clicking on the Standby button, with some message like "You have open SSH sessions".
