You know the active edges and corners. Great thing. But one Action is missing in the screen corners: "Prevent Sleep Mode" (and maybe also "Prevent screen Saver"?) When you e.g. upload a big file over the browser, you don't wan't the system to sleep. Sure, you can activate the checkbox somewhere. Bit an active corner for that would be very neat. IIRC apple has this feature on the corners. Thanks Andreas Maybe a wrong sub module of plasma here what I chose. Then pleas move to the correct group. kudos.
This is theoretically possible by adding the existing manual screen locking block to the list of actions There's also been a request on the KDE forums for similar functionality (inhibit screen locking for x minutes) https://discuss.kde.org/t/manually-block-sleep-and-screen-locking-for-n-minutes/14560/2
