Whoops, it's already been months since I last blogged. I've been actively involved with Plasma and especially its power management service PowerDevil for over a year now. I'm still learning about how everything fits together.
About selected PowerDevil work in Plasma 6.2 and brightness controls in particular.
I really like this feature with BetterDisplay on my MacBook from work - and now it is coming to Plasma, too - that’s great! :)
