This release brings probably one of the features I've been most excited about for a long time now. I'm jazzed that we can finally customize the colors of the title bar, tabs and a whole lot else to a whole variety of new values. They can automatically match the terminal body itself, for a seamless look, that I've been totally infatuated with since I first saw it.<p>And it's all configurable, so we're not forcing any UI changes down anyone's throats. If you don't like the tab matching the terminal body, then just change it. Or change the titlebar colors. It doesn't matter - it's your Terminal, do what you want with it.<p>It opens the door for more configurations like this in the future too. As with most engineering problems, laying the architecture in place is most of the hard work.<p>Maybe not the most exciting feature for many, but one I've been passionate about for a long time.
