There seems to be an opportunity here for platform vendors like Microsoft or Apple to be a bit more aggressive about "this application is what's slowing you down" notifications. (With the ability for the user to say "yes, I'm editing a 4-hour movie, don't warn me about this app again".)

Don't Apple already do something similar for battery hogs? May be misremembering, but I'd have thought a similar principle applied.

Half the challenge of course would be dissuading the vendor from excluding their own apps from these notifications.

Microsoft did something similar for every browser that wasn't Edge.

But yes, on OS X, the battery drop-down will list any apps that are consuming significant amounts of energy. For me these are constantly Chrome and Intellij IDEA.

Well, JetBrains is one of few choices that's even more of a hog than Atom.

Does Atom provide a GUI, ER or UML designer out of the box?

I don't know. Atom is too slow for me as well. I generally use VS Code or just VIM.

Once I wanted my desktop's features in a phone. Now I want my phone's features on my desktop.
