All I really deeply want on this front is for the ability to have my IDE and CLI apps specific colors for specific projects. On mac, being able to 3-finger swipe up to mission control and then swipe down on the app I want has been by far my favorite way to navigate windows. The main problem I have is that the color of the app itself is the main way of telling them apart. I wish I could use a particular VS Code or Terminal theme for just one instance
