So Linus on the WAN show last night was talking about how he had trouble diagnosing why half his pc's weren't going to sleep. He eventually figured out that it was because half the pc's had steam running but on a store page, which means a video is playing.
Meanwhile, on Linux: #KDE plasma just has an easy built-into-the-ui indicator that tells you what is blocking sleep .... I have used this feature many times and I love it.
So yeah, I don't know who at KDE worked on this feature, but I ❤️ you
