This is probably the biggest thing keeping me from switching. Other apps almost feel claustrophobic with how little of the screen is used. At least last time I explored.
Edit: just tried again and Summit is pretty close I guess.
Edit: answering my own post now but with some customization that either didn’t exist before or I missed I have gotten even closer.
Connect can look exactly the same if you set it that way. And it can switch what side the thumbnails are on. I use it like this, though I leave the buttons enabled so it’s slightly less compact than this.
