Let's talk about the new Slack. The crowded title bar (with the hamburger icon, the search box, and now even the profile icon) means you can only grab it for dragging in two specific zones. Even worse, the window cannot be dragged at all when search is active, as the title bar gets completely overshadowed by the search popup. Absolute trash of an UI.

IntelliJ IDEA also fell victim to this trend of abusing the title bar, but they are be reverting the change and providing a setting after listening to the inevitable criticism: https://youtrack.jetbrains.com/issue/IDEA-219212
