What if IntelliJ IDEA and WebStorm could gray out unused object properties in JavaScript/TypeScript? Useful? Annoying? Surprisingly handy? Thinking about shipping this inspection — and maybe live-streaming how it’s built. Would you use it?

OK, that’s really cool - Spotify introduced DJ X, your AI assistant for composing a playlist that you’re going to listen to in the current session. It behaves also like a radio presenter, describing what you just discovered and what’s up next. Spotify, good job on that!

A kill switch that restarts your IDE isn't the best idea, but we've already filed a feature request to explain why we mark plugins as broken, so users are aware of why we're taking something down. Thank you for keeping an eye on that, Brice!

Correct! We've extracted JCEF from JBR+JCEF into a separate plugin and published it to JetBrains Marketplace. Now, i.e., Mermaid plugin — already having a dependency on JCEF module — will download that plugin for you when using a newer Android Studio release. Completely transparent process!
